Since Twitter rolled out the 280 character limit, my timeline has been destroyed. All of the charm and cleverness that the service once had is gone. I follow around 295 people ... about 25 have them have quit Twitter (since T___p was elected), and a half dozen or so have unfollowed me since I said I'd block anyone who tweeted >140.
This month I will systematically go through my following list and unfollow anyone who is tweeting over 140. I might end up following no one this way, but so be it. You can rest assured that none of my tweets will ever exceed 140 characters.
