BloggingOn 7.3 - My Favorite Wiki

Not that I'm intimately familiar with more than... well, any of these things, but this wiki that I mentioned in passing gets my unqualified approval. It may not address a topic as significant as a global epidemic, but it makes good use of the medium: this is a topic that has not yet been exhaustively researched, and due to the constantly growing volume of material, a wiki seems like the obvious choice for building a solid base of (collective) information.
