Hello! I'm looking for some kind of platform to build a blogging community around (in style with: Wordpress MU, Twitter etc.). The most important thing is that it should be suitable for mobile devices, and it should be clean & simple. I started with WPMU but i couldn't find any themes for mobile users, as I want the theme to be strictly for mobile users. I've also been looking at som projects over at sourceforge and I found a couple intersting ones, however they are all more or less dead in terms of activity. So any suggestions?
