Stumbleupon Stumbles Onward

Stumbleupon is a browser plug-in to suggest sites of interest, based on a user’s interest in a range of topics. I’ve never used it, and that pretty much sums up my knowledge of it… but I’ve seen it quite a bit in my referrer logs, both here and at Dogcaught. Today I saw this article which indicates they’re about to officially launch publicly and unveil an IE version of their software.
