Wikipedia.org

Despite repeated attempts to compromise its integrity, Wikipedia remains the most popular online encyclopedia on the Web. Since anyone can create or edit a Wikipedia page, both companies and individuals have been caught airbrushing and embellishing their own entries. The Wiki community usually intervenes, however — egregious edits get reported on WikiScanner and Wiki trolls are given the heave ho — or at least a Wiki humiliation. Now you can even enjoy Wikipedia's wisdom without ever clicking on it. The Microsoft Live search engine automatically pulls up the first paragraph of any relevant Wikipedia entry in its search results. And a new print-it-yourself travel guide called Offbeat Guides (still in beta as of June 2008) culls information from the site to create custom travel guides tailored to the exact dates of your trip. Now that's neat.

Yahoo! Finance

A haven for armchair investors and money junkies, Yahoo! Finance has everything you need to keep up with business — news, stock-specific research, charts, even press releases. In late May, Yahoo! Finance resumed free real-time quotes instead of the standard 20-minute delays on rivals like Google Finance. (The service had been suspended a couple years ago in a dispute with the major stock exchanges.) Power brokers can shell out $10.95 a month for real-time stock charting. For all the criticism about Yahoo!'s failure to innovate, its finance site showcases the best of what the company has to offer.

Craigslist

Its elementary page design has barely changed in 13 years, even as newer, flashier competitors vie for a chunk of the $15 billion online classified market. But so what? Craigslist is a Web pioneer that will never go stale, and remains the essential site for want ads ranging from real estate and used furniture to jobs, romance and one-night stands. Craigslist launched in 100 additional cities this spring, making the site's services available in over 500 cities in 50 countries. To stay ahead of other newcomers with a strong international presence — including Kijiji, Oodle and OLX — the venerable Craigslist now makes its listings available in Spanish, French, Italian and German in some cities. This way, you can't blame the language barrier for fumbling your "missed connection."


ESPN

ESPN is synonymous with sports. Die-hard fans come straight to this megasite for scores, schedules and analysis, then hang around for the video highlights, games and podcasts. Over the past year, ESPN has beefed up its fantasy sports league offerings and high school football coverage, and it's now pulling in news from college fan sites too. If you can't bear to leave your sports news at home, sign up for "ESPN Alerts" by text message and download small-screen videos.

Yelp

If it's a restaurant, shop or business, it's probably been reviewed on Yelp — an independent site with millions of user-submitted evaluations. Yelp's got a gaggle of rivals — most notably Yahoo! Local — but it's the only one that lets reviewees talk back. After businesses complained about their reputation getting trashed by careless reviews, this spring the site began allowing proprietors to e-mail reviewers directly, make instant changes to their company details on the site and see how many people have visited their Yelp listing. For you, that means more rounded and accurate reviews.

Facebook

If MySpace is a PC, then Facebook is a Mac. The former may have more users, but the latter is classier and cleaner in design. Facebook also makes it super easy to find people you know, and it has won more fans among professionals and the thirtysomething crowd. The site has more than 30,000 add-on applications — among them, games, interactive maps and quizzes — to bling out your personal page (or spam your friends), and a redesign planned for later this year will restore the tidy Facebook look that the add-on apps have begun to clutter up. If you're on the hunt for new social networks to ply, check out upstarts Bebo and hi5.

Digg

Say you stumble across a news story you like. You "Digg" it, by clicking a link at the end of the story. The more people who Digg the same story, the higher it rises in the popularity ranking on Digg.com, where other Diggers can read and comment on it. While comments often read more like rants, they serve as an excellent barometer of the issues Web surfers are most interested in. In May, Digg announced plans to collaborate with Facebook, to let users see which of their Facebook friends also have accounts on Digg — as well as which stories they Digg. Next up: a planned recommendation engine that will suggest stories you might like based on your past Diggs. Handy upgrades like these should help keep Digg from getting buried by competitors such as Mixx and Reddit.

Google

Much more than a search site, Google has become the Microsoft of the tech world. Google Docs offers free spreadsheets, word processing and presentations. Photo-based Google Earth now operates inside a browser plug-in, no longer requiring a lengthy download to your desktop. You can even run Google on your mobile phone, including the iPhone. Next Google wants to help you get more out of your online social networks: its Friend Connect system, due out later this year, will make it easier to interact with your network contacts, even on remote sites. So, for example, Friend Connect might show you which of your Facebook friends also use the community music site last.fm — with your permission, of course — allowing you to share your favorite music with them more easily.

TMZ

There's no better way to spread gossip than to put it online. Sure, it's tacky, rude and unreliable, but TMZ is the most popular gossip site on the Web because it is chock-full of juicy celebrity tidbits, photos and videos. Check it out — it can help your otherwise dreary workday go a little faster. TMZ also breaks more stories on Britney, Lindsay and the rest of the Hollywood gang than any other gossip site. If you're still thirsting for more, you can watch TMZ on TV (find local listings here. Or read on at E! Online, Perez Hilton and The Superficial.

Flickr

Digital photo–sharing sites have come and gone, but Flickr has remained. It offers some of the smartest tools for managing your ever expanding picture collection — from Photostream, which lets you scan your pics quickly, to a newly added video tool for pro users (who pay $25 per year). We also dig Flickr's photo-editing capabilities provided by Picnik. Our quibbles: users who do not pay the annual subscription fee can upload only 100 MB of content per month, and Flickr's Photostream doesn't arrange newly added pics by the date the photo was taken.
