I’ve been looking for a hosted blog platform since last year and I’m now trialling posterous.com. Importing my wordpress posts was incredibly smooth and I’ve manually carried over some of the pointers to projects and popular posts with a bit of manual effort. The theming looks to have advanced hugely since I last checked and might be possible to convert my wordpress theme with a bit of effort. I’m not sure whether I will do that or not, I’m quite liking the plain default theme.
I’m going to trial posterous for a while before deciding whether to switch over completely.
I’m using the posterous iPhone app to write this which means there will probably be loads of typos - I’ll apologise in advance :)
