I hate it too, but the UI is about discovery. Facebook stopped being cool when they stopped focusing on colleges and opened up to everyone. There's nothing wrong with that, boring companies tend to make more money than cool ones. But Snapchat wants their content to stay cool. Snapchat's UI was designed specifically to keep those who are not tech savvy from deeply using the service, which in theory would lead to better content as those who take the time to really understand the product make use of all the features.
