I don't think a 'new version of old Facebook' can succeed in the medium term, for a few reasons: 1) I don't think a platform can get enough critical mass like Facebook did. It's much easier to get a smallish circle of people (5-20 people) to align on one platform and use a group chat than it is to get everyone you know to align on the same platform. 2) The rise of mobile. Things like having an individual profile made more sense when sitting at a laptop/desktop PC and actively browsing someone else's content. With mobile, there's more friction to viewing profiles, so the feed model tends to win out. 3) I think many people are more apprehensive about posting content to a wide audience than they were in Facebook's prime.
