This question was raised today at online bootcamp: Does CoTweet.com have Facebook integration like Tweetdeck?

Ping.fm integration is available –very new since Oct 23— so that what you tweet on co-tweet can flow to your ping.fm account which of course flows to all of your accounts configured there.

Stay tuned for a detailed blog post on this subject.
