Great feature on Posterous! If you've never used Posterous, you should take a look. It is a blog platform that allows you to post by email but comes with a few key features for those users that are active on many platforms. The most interesting of these features is the autopost feature that allows you to post to Posterous and have it autopost to all of your other profiles.
I have used Ping.fm for clients in the past to auto-post to other social profiles, but it doesn't compare to the easy of use on Posterous. It took less than 10 minutes to add my accounts and I didn't have any snags with Facebook. Ping.fm took me weeks to get both the personal profile and Fan Page integrated and a few days later one would work and the other would not. This is the first post to test how it propagates across all of my profiles. I will follow up with a second post to share the findings. Fingers crossed!
