The iOS app is still crap compared to the web experience. Users can't edit, or even delete, their own comments. The length of time for likes and comments to appear is unpredictable. Sometimes very quickly, sometimes users don't see their own comments for half a minute. Art is displayed oddly. It's almost always clipped at top and bottom on the page, requiring an extra step to actually see it. They seem to be under the mistaken impression that mobile users are like Twitter users, firing shots into the darkness, instead of curled up on their couches with iPads, composing little essays and looking at family photos.
