Just wondering: how can somebody start again something he worked already years on? I understand that you might learned a lot with Posterous and now you'd like to just employ that knowledge in a new blog project. But is it not a bit dangerous to stick to the same thing over years? You could loose time and after ten years looking back and you pity that you just worked only on blog systems. I don't want to talk blogs down, they are a very interesting use case and I still think there's room for improvement but in terms of spreading the bets and just the need to start something totally new I am a bit confused that you do the same thing over and over again (and I didn't see any disruptive feature or new angle with Posthaven).
