I'd pay $10/month for Tweetbot. It is an ad-free twitter experience after all.
Well Tweetbot will be paying Twitter $11/mo. For them to also make some money, they have to charge you closer to $20/mo.
Tweetbot will not pay that, they'll poll instead of stream and have a worse product because of it.
Tweetbot with poll still beats Twitter.com with streaming.
I think polling instead of real-time. The timeline has decent rate limits, but I can't understand if the Direct message is rate-limited globally for the app or not?
