The problem with Posterous is that the changes they have made over the past 8 months (since I started using it) have been small and irrelevant things (like code highlighting or such stuff).<p>When I write, I want to be appreciated and I want my writing to reach a big audience. Tumblr achieves that, posterous never made any change in that direction.<p>Posterous started off cool and fresh, but that initial slew of innovation has not been followed up on. Things like the backtype widget, view count, etc all were there from the start, and later not much new stuff came after that.<p>Posterous have focused too much on these technical stuff (like CSS buttons), and too little on the social stuff. I write for people to read, not for my page to look good.<p>Don't get me wrong, I like posterous a lot. But I just think posterous is simple by being limiting.
