Will take getting used too, but seeing all my networks in one is growing on me. The only problem with that is my friends sometimes post the same thing to twitter and Facebook at the same time. Though I guess I'd still read it twice anyways!
Is there a quicker way to see my lists other than clicking the friends button then my twitter account, then select the list?
It seems to update as and when an update happens too. This is the same for the newest desktop TweetDeck when you sign up for it, brilliant feature, rather than updating every hour or whatever you set!
