Good old Prekomorec here at Blogger seems to be getting a bit ... behind the times. Dunno, it just doesn't look as pretty as some of the things to be seen at Tumblr and Posterous, so I'm going to be trialling those two platforms over the next few days.
So far Posterous definitely seems much simpler, but some of the Tumblr blogs and social features seem prettier. We'll see, we'll see.
Update 1: 04.05.2011 ~> for now Posterous is looking much simpler, plus it lets viewers see full size images.
