As far as I can tell, they're closed down ... their blog (http://diomedeblog.wordpress.com/ http://diomedeblog.wordpress.com/) has been inactive for over a year, and as far as I can see there's nowhere for existing users to log in (they had open signups at one point last year...) Edit: Actually, it looks like they closed on Mar 19, according to an email they sent to existing users. They say they might reopen "with a new approach" near the end of the year.
