I just now made the acquaintance of this site... and might have found something new to do, LOL. While I'm skeptical of using it as a research tool, like irishgit, I'm certainly not opposed to using it as a quick source of information, if you're willing to accept the risk. I browsed a bunch of articles in my field and found nothing terribly wrong (a few misspellings but the articles were factually accurate). Since there's a bunch of stuff that I couldn't find, time to start writing! I think Wikipedia is a great idea: let's try open-source not only in code but information. Very fun and useful. UPDATE: crank it up to five stars. Wikipedia is amazing, and somehow it has managed to attract some of the brightest minds in every field. So much still needs to be compiled and written. The internal peer-review mechanisms seem to work very well, though you still need to be a bit cautious about using the information presented here. I see a new addiction developing for me ... **FURTHER UPDATE. I've come back to Rateitall for a while because I needed a Wikibreak. Almost all of my online time in the last ten months has been spent on Wikipedia, where I have written about 250 articles from scratch in the area I did my Ph.D.; Wikipedia is really one of the most fun places on the internet if you have some expertise about something and you like to write. It's the *opposite* of Rateitall, though, since RIA is an opinion site, and Wikipedia rigorously enforces NPOV (neutral point of view). Check it out.
