No. It never has. As I am guilty of not reading threads/posts in full and changing topics, completely diverting the original posters' goal of discussing whatever it is they intended to discuss. Run-on sentences FTW. Sentence fragments FTW.
Sylar, Harold, and Shaun of the Dead from Star Trek, FTW. (Discussing the movie is much more entertaining than political drivel over the intarwebz).
