I always thougth Route by George Oppen was the ultimate IA poem, but Edward Houseman’s writte a little gem.
“From the September issue of First Monday. Compares the search experience of three different interfaces, including one they’ve designed that looks fairly similar to the one at MSDN. They found out (big suprise) that theirs works best. Might be an example of where using frames is actually a good idea.”
don’t forget– tonight!
