I'm looking into Posterous and the tight integration within their platform. So far it looks pretty interesting and useful. I probably will not be happy enough with rich emails composing from my Mail.app, but we'll figure this out later.
I'll keep running my blog on live.prokhorenko.us for whatever it takes, and anyway Posterous known to be good at handling own domain name for blogs. It will stay linked to Blogger yet.
They still miss comments integration with disqus, and I think they don't have a better way to work feedburner's feed, but it looks like they are moving forward in this direction, too.
So talk to you later.
