If I'm flipping through television channels and come across one that I really dislike, the idea of 'blocking' that channel never enters my mind. I have no urge to contact the TV station and voice my disapproval. I just move on to the next channel, which is the quickest and easiest solution. Why can't people do the same on internet forums? Why do some feel compelled to waste their time responding to posts they don't like, or tattling to a moderator?
