does it though? do you really expect this to be a success? people will just stay on reddit like they always do. twitter has been taken over by one of the most hated people in the world and they appear to be doing better than ever user-wise
I think current Reddit is very different from what Digg was. Reddit is too much user generated content (i.e. the exact same AskReddit questions asked on a weekly basis) and not enough cool links/videos anymore. At least on the non-logged in homepage. If Digg is exclusively links, it'll definitely have a place imo.
obviously it massively depends on what subs you follow, but yes this is the problem with reddit. it's completely antithetical to long-form content that builds over time.
