Prior to this month, about 5 people had bookmarked my Poincare Project on del.icio.us. Then in the last week, 80 people have bookmarked it!
I better get back to working on it! :-)
UPDATE (2006/09/09): The source of recent interest seems to be a post to Ars Mathematica and a post to reddit. Not sure which came first but the former lead to a couple of hundred hits and the latter a couple of thousand.
