11. Etsy.com

Etsy.com, it’s a website where anyone who makes their own items can set up shop and, for a nominal fee, sell their stuff. You can buy handmade clothing, original artwork, prints of artwork, baby clothes, cookies and brownies and cakes, handmade books, handmade jewelry, pottery, furniture, and much more.

1. Flickr –  Flickr was the first site to solve this problem with something called collaborative tagging. The idea is that if everyone is allowed to tag everyone else’s uploaded photos, then a rough-and-ready categorization will naturally emerge from the wisdom of the crowd. It works because it has to — there aren’t enough librarians in the world to look after Flickr’s archive of 3 billion photos, much less file them away for future reference.
2. California Coastline –  The site is simply what it claims to be: 10,000 up-close-and-personal aerial shots of the entire 1,000-mile-long coast. You can see everything from Barbra Streisand’s Malibu backyard to the best secret surf spots the state has to offer just past the off-limits Vandenberg Air Force Base.
3. Delicious – Delicious (formerly del.icio.us) started out as a kind of Flickr for bookmarks (it’s no coincidence; Flickr and Delicious are both owned by Yahoo!) but is now more useful as a search-engine hack. You filter Delicious’ tags to drill down to the type of content you’re searching for.
4. Metafilter – There are lots of collaborative voting and comment sites out there —Digg, Reddit, StumbleUpon — but there is only one worth joining, even if it does cost $5: Metafilter, or “MeFi” for those in the know. In fact, that fee ends up feeling like a feature rather than an impediment, because it manages to keep the site remarkably free of trolls, griefers and other anonymous jerks. As a result, MeFi has the public-spirited flavor of a small town or good university, and the answers on AskMeFi can be helpful.
5. Popurls – The hardest thing about getting news from the Net is keeping up with it. First there were browser-based bookmarks, but you had to check them all the time. Then the RSS reader was invented, which brought the news home by asking you to subscribe to feeds from your favorite sites. Invariably, they stacked up, unread. Then popurls (it rhymes with popular) cracked the code by pulling together up-to-the-moment headlines from the biggest and most popular news and opinion sites, blogs and vlogs onto one giant Web page for you to graze through.
6. Twitter – “The one thing you can say for certain about Twitter is that it makes a terrible first impression,” wrote Steven Johnson in his TIME cover story on the micro-blogging site, and it’s true: you’ll either love it or hate it. Haters maintain that nothing worth saying can be said in 140 characters.
7. Skype – With cell-phone minutes being so cheap, Luddites wonder what the big deal is about making phone calls over the Internet — or as geeks call it, VoIP, short for “voice over Internet protocol.” The answer is that VoIP has the power to turn an Internet connection into a videophone.
8. Boing Boing - Boing Boing functions as a proxy for the entire aesthetic of the Web. It’s a deliberately eclectic mix of tech commentary, sci-fiction nerd-outs, fringe culture, gadget porn and serious news items. It is, according to its own description, a “directory of wonderful things.” The four editors and writers behind Boing Boing will fiercely dispute this, but the site’s dirty secret is that it’s about as mainstream as it gets — for the mainstream of the Web, that is.
9. Academic Earth - The latest campus revolutionaries are the so-called edupunks — and their mission is to break up the ivory tower so everyone can pile into the classroom. MIT was the first university to heed the edupunk call: it started posting syllabi, course notes and videotaped lectures on ocw.mit.edu back in 2001. Harvard, Berkeley, Yale, Princeton and Stanford soon followed suit, with their own schemes for posting videos of their most popular courses.
10. OpenTable – OpenTable does one (seemingly trivial) thing: help you make a restaurant reservation. But it does it so well that you’ll wonder how you ever lived without the site. What kind of food would you like? When do you want to sit down? Here are your options; click to reserve.
11. Google – A decade after its birth, Google has achieved such ubiquity that it’s easier to say what it isn’t than what it is. But let’s try to define it anyway: Google is search, e-mail, telephony and a full suite of Web-based G-ware (with a word processor, spreadsheet application, calendar and contacts manager). But wait — there’s more! Google sub-brands such as Blogger, Picasa and SketchUp could argue their way onto any best-of-the-Web list on their own merits. Depending on your point of view, the company’s many tentacles make Google the best thing since dancing babies or our future alien overlord. The only viable alternative to Google’s search technology is Microsoft’s just-released Bing
12. YouTube – Another indispensable site owned by the Google borg, though the bulk of its content — cute cats, jiggling body parts and stupid human tricks — is plenty dispensable. But you never know what gems you’ll find buried under all those America’s Funniest Home Videos rejects. And from such dross is true art made. Witness ThruYOU and In B Flat and consider this: Is YouTube a tomb where the image that Eadweard Muybridge captured in 1877 goes to die? Or the cradle of an entirely new visual language?
13. Wolfram|Alpha - A long, long time ago, in a galaxy not so far away, Google was just two grad students at Stanford with a smart idea for search technology. Today’s search whiz kid is Stephen Wolfram, one of the biggest brains on the planet — and he’s got the new idea. Wolfram has developed a search engine that can actually understand your questions and try to figure out answers. It takes some doing to learn how to talk toWolfram|Alpha, but it’s well worth it.
14. Hulu – Determined not to let what happened to the music industry happen to Hollywood, NBC and Fox teamed up to finance a site that gives Webizens what they want: free TV and movies, streamed in high quality, on demand. (Shrewdly, the networks have kept their logos, and their legacy issues, off the site.) Think of it as a TiVo subscription without the set-top box or monthly bill.
15. Vimeo – There are gems just waiting to be discovered on YouTube, (search “althea and donna” for one of millions of examples). But if you’d rather find Kanye West uploading his stuff — in high definition, no less — then search for the user name “kwest” on Vimeo. Lightly curated content and a reputation as the hangout for serious creative types keep the quality on Vimeo remarkably high.
16. Fora TV - Whoever said television makes you stupid never saw Fora TV. Every day the site’s programmers upload clips of scientists, authors, intellectuals, captains of industry and world leaders standing up and laying out what they think they know. The feeds are piped in from Davos, the Entertainment Gathering, the World Economic Forum — all élite conferences where smart people gather to tell one another what they’re thinking, planning and doing.
17. Craiglook – Craigslist is on everyone’s short list for most useful website ever, but at this point, it’s embarrassingly retro. The Craigslist logo? A peace sign. The user interface? Text-based. The search function? A primitive command line. Craiglook remedies those things by adding all the Web 2.0 bells and whistles we’ve come to expect to Craig’s underlying listings data. It’s not an alternative to Craigslist — it’s a remix.
18. Shop Goodwill - Now that everyone knows about eBay, the auction site is not the bargain hunter’s paradise that it used to be. On eBay you always find what you’re looking for, but so does everyone else — and that drives prices up. The solution is to fish in a less crowded pool, and one of the largest charities in the world, Goodwill Industries, has a little-known auction site filled with treasures. Unlike on eBay, the people selling stuff on Shop Goodwill often don’t know what they’ve got, so great deals abound.
19. Amazon – Amazon is a virtual store with infinite shelf space. Its sheer size makes it the default market maker for just about every product sold online, and thus it sets the prices to beat. Text a UPC code (that string of numbers next to the bar code) to “AMAZON” and you can even check a price when you’re out in the real world and think you’ve spotted a bargain. But don’t stop there: thousands of competitors and myriad price-comparison engines allow you to shop them all at once.
20. Kayak – Which travel site should you turn to when booking plane tickets: a) Travelocity, b) Expedia or c) Orbitz? The answer is d) All of the above — by using Kayak, a meta-search site for travelers. Kayak scours more than 100 search engines in order to find the lowest possible price. One tip: before you buy from any travel site, always check Southwest.
21. Netflix – If you have a DVD player, odds are you already know about Netflix’s excellent movies-by-mail service. Netflix is morphing into a similarly excellent streaming-video service, but that’s no reason to forget the mailman’s name. There is an array of niche “flix” companies that specialize in delivering media to your door. SmartFlix specializes in how-to tutorials; Fight-Flix, in martial-arts  videos; BookSwim and Paperspine,  in books; and, dwarfing them all, GameFly, the Netflix of video games.
22. Etsy – Etsy is the long-haired, Birkenstocked love child of Amazon and eBay. It’s a crafts-only marketplace oozing with personality — imagine if Martha Stewart were reincarnated as Ani DiFranco and you get the gist. It’s the go-to site for handmade fashion, furniture, toys and housewares. Like with its corporate forebears, there are plenty of photographs, seller ratings and payment options — but it still feels intimate because Etsy sells labors of love from actual people.
23. PropertyShark.com -  PropertyShark.com is a free service that culls an incredible amount of data for houses in the big, coastal population centers, plus Texas. The PropertyShark database, searchable by address, tracks price history, comparables, tax-roll information, owner names, demographic information, flood and fire maps and more. A subscription buys even more information, including lists of foreclosure auctions and pre-foreclosure notices — even phone numbers of property owners. By the time you make that call, you may know more than he does.
24. Wikipedia – In 2004, the editor of the Encyclopedia Britannica wrote an article called “The Faith-Based Encyclopedia” in which he compared Wikipedia, the online encyclopedia that anyone can update and edit, to a public toilet. The following year the world’s most distinguished scientific journal, Nature, decided to compare Wikipedia andBritannica in a blind taste test. Nature‘s conclusion? That Wikipedia and Britannicaare roughly equal when it comes to accuracy. That finding is disputed by Britannica. Naturestands by its story. And Wikipedia, of course, documents Britannica‘s beef with Nature in a mind-numbingly complete wiki entry.
25. Facebook – If you’ve been avoiding Facebook because you’re concerned about privacy issues or worried you’ll lose your life to social networking, you’ve already spent too much time thinking about this behemoth of a site. Although it’s desperate to be more, Facebook is really just a phone book. It’s where your acquaintances, friends, friends of friends and people you’ve met only a couple of times go when they need to find your e-mail address. While they’re looking at your page, they’ll be reminded of what you look like, your dog’s name and your hometown — the kind of stuff that makes small talk easier. So go create a page, upload a picture and provide answers to questions you’d be comfortable revealing to a new acquaintance. Then “friend” the people you know. It’s easy, takes a minute, and frees you to stop obsessing about the necessity of Facebook.
