If all you've been hearing lately (even here!) is news about Facebook, Google, and Wikipedia, it's about time to mention some alternatives I've been tracking.
Citizendium: a wiki for people who can't stand the rules of engagement established by Wikipedia's founders about NPOV or" neutral point of view." This alternative doesn't let people use pseudonyms such as "WizardDuck," and welcomes the general public and experts -meaning those who represent organizations, including professional communicators, PR agencies etc. It has lofty goals, to "soon attempt to unseat Wikipedia."
Mahalo: The human-powered search engine as it calls itself. "Say goodbye to spam, mediocre content and deceptive sites," it says, taking a thinly-disguised whack at Google. Search results are built in a "greenhouse" where style guides and part-time guides manage content.
One more alternative if you're thinking about creating your own Wiki.
WikiSpaces: Despite the goofy logo, it's an easy to create wiki for any personal project. Just like PBWiki, and Wetpaint, but with a lot more intuitive functions.
