BlueprintCSS 101

It's not clear what are the advantages of BlueprintCSS over Yahoo's YUI Library CSS tools, e.g. the YUI Grids (http://developer.yahoo.com/yui/grids/) and the grid tool. YUI has plenty of documentation and has a lot of eyeballs to test it on different browsers. The Yahoo team size seems like a big advantage of YUI CSS over BlueprintCSS.

This is neat. We can hope for more entrants in the "CSS platform space" -- the base-line for web site usability will improve as a result, as most designers will be able to move up to a higher level of "typographical abstractions" without getting stuck on one or two bit-rotting libs.
