Love posterous even more

The recently released groups are already awesome. I love the possibility to quickly switch between the 'regular' site and the groups-site.
Beta for one week for crowdsourcing and bugtracking ... and then releasing it. Talking about fastdevelopment!
And the Posterous Android app, which i'm using to post this, is also extremly easy to use. Big WOW is the easyness to post accross different Posterous sites.
