That looks like the culprit. :)

This works, but just as a general guideline, its probably not a good idea to grab a nested subview's frame, since the parent view might do something to change it.  In this particular case it works but, it would be cleaner if we could either get the width from the cell, or maybe avoid having to pass the width at all. 

In `layoutSubviews` the post view's width is adjusted to account for left and right padding.  What do you think about changing `configureCell:withWidth:` to just `configureCell:` and letting the method calculate the width as is done in `layoutSubviews`?
