Ugly design
Ugly, ugly icon. But thats not whats the most important, because its only a matter of taste. The most important is that this apps desing is just plain unreadable. Everythings cluttered, there is no air here. I cant see why its supposed to be better than the Twitter native app. Tweetbot looks like it was designed by a thrifty, if not miserly, people.
