OK, good job creating the tweet view and augmenting the API to support retweet, etc. Might be nice if there was a visual indication that the retweet happened.

In heightForRowAtIndexPath, don't create a cell just to get the size. That's very expensive. Instead, consider having a class method to calculate height.
