apparently according to my friend. Derpy cute pictures are more eye-catching and more brohoof worthy than an actually well thought out post. (This is just for comedy purposes. Me and my friend are good well friends!)
XD. It actually makes sense. People don't want to sit through long well thought out comments. They want something quick and simple to read. Also the picture acts as a eye-catcher and because of the person get more brohoofs. As people more people are reading your comments.
