The one thing I wish it allowed was multiple accounts — not multiple blogs on a single account, multiple accounts each the with option for multiple blogs. The WordPress app already has this feature which make it even more of a drag that the latest version of their app won’t even open.
All that being said, I’ve still been trying to figure out where Posterous fits in for me. When I was still using VOX.com, and on the rare occasion I would actually post something, I was using Posterous to crosspost to there and WP. Now I’m not entirely sure.
In the mean time I’ll just keep playing with it with hopes it’ll show me. ?
