I feel bad for Kevin, to be stepped down from his own startup, it was his idea, it was his money, and now some VC guys just throw him out of the window. I don't believe Kevin just stepped down because of the V4 fail. Specially when he just became CEO again a couple of months ago.
Digg just became a zombie site, as a user, everytime I visit I feel like i'm visiting my RSS reader, it just doesn't feel to have any human interaction except for the comments.
Would it be pretty bad if they rolled back to V3 ? I mean...this version 4 is really not working out for anyone.
