Finally I came to the point that I do not see much sense in keeping up my Blogger account any longer.
Posterous became a great replacement, I found myself using only it, with broadcasting everything to all other points of presence, so why keep it secondary, while it's the deal maker. And it keeps much more history in it, comparing to Blogger, which keeps only its own story.
I would keep my Blogger (prokhorenko.blogspot.com) account anyways, but it's not going to be serving my live.prokhorenko.us domain name anymore.
Have fun and don't be angry of some posts reappearing again in the feed - shit happens.
