I like the way direct messages work -- the design choice to make them "threaded" is, I think, a good one. And a safe one given that Apple assumes text messages should work that way on the iPhone.

My problem, however, is that using Mail.app is more effective for checking on direct messages. It seems like Tweetie doesn't poll for updates enough, and it will be up to an hour (guessing) until I'll see a freshly-posted direct message.

Is there anything that can be done about this? Is there something I can change to have it update more frequently?
