If you've never checked out Wikipedia, it's an online encyclopedia, but unlike its counterparts, it's maintained by open source editing, which means that anyone with enough interest or knowledge is free to add to it. The two biggest advantages of this are that its extremely up-to-date (same day full account of Pope's death) and unlike typical written ecyclopedias, absoultely anything and everything can and probably will be included. I read EXTENSIVELY about graffiti last night and just learned about ball lightning. I usually research something everday and have yet to be disappointed. From Neil Young to Burning Man, Tibet to Atlantis, Shotokan Karate to Tantra. Knowledge rules....
