Posterous "RSS for My Subscriptions"
Posterous email notifications for subscriptions are nice, but I always use Google Reder for that purpose. I have posted to Posterous team with question about feed of all subscribed blogs. In that time the only way to have notifications in Reader was to subscribe to RSS on each Blog. In that case there was no reason to subscribe on Posterous, and email notifications are pointless.
After about two weaks on "My Subscriptions" i sow (see image) RSS for all my subscriptions!
