Welcome to WordPress. Fifteen million Posterous users have had to find a new home after Twitter nuked their old one. I am a wanderer myself, but I have alighted for now, and all my Posterous posts have come with me in my bindle.
Perhaps I should have gone with Google in the first place, like Contrary (David) Brin, but it seems there’s hardly a more stable blogspot on the Web than WordPress — after all, Google shuts down its projects with regularity. We’ll see.
