I also agree that this is the right way to go.

FWIW, the CUFP talk that started this discussion took the current 
text out of context.  It is one thing to have the fp-speak 
description of Haskell in isolation (as in the CUFP talk) and 
another to have it on the wiki front-page, where the side bar 
advertises libraries, applications, etc. and the middle has news 
items and so forth.
