I was the creator of the OG Popurls which at the time was the #1 traffic driver for Reddit and Digg; and also created Twidroid the very first Android Twitter client which became one of the reasons for shutting down 3rd party apps after its acquisition. Since I'm a sucker for anything old-school Web, I've been working on a Digg 1.0 rehash for a while now so if any of you wants to beta test let me know.
Speaking of old school web, I once got on the front page of Digg with a mock-up of what Digg would have looked like in the 90s. Sadly that seems to have been lost in the sands of time.
