Yeah they're essentially identical platforms in terms of interaction. Reading a stream, replying, retweeting/reposting etc...

They already have multi-user support, I'd rather interact with one app in this way. Or better, have the client merge your two accounts so that app.net/twitter become seamless and instead of thinking about who is on where, you simply enjoy it through the window of your client and none of that matters.

But.. I'm sure it took some good work to develop this and by simply updating Tweetbot they might not get reimbursed for that dev time. Rather, the new app must've been required.

I look forward to an integrated client down the road.
