This is a mockup I’ve just came up with, that would be good for Twitter App’s. However if your one of those people who follow 100’s of people then this wouldn’t be very good, unless maybe for direct messages on Twitter.
The font isn’t perfect as I didn’t use Photoshop so no shadows were placed on the text but as you can see it would be a good way for Twitter App’s to push tweets or direct replies/messages.
Update: Here’s a second mockup which would appear if you get multiple tweets.
