Maybe I'm wrong, but I think some of these 'simplistic' posts typically result from those who aren't totally familiar with the way discussion forums work. It seems to me that certain posters think of Muppet Central as a Facebook chatroom.
I've actually been wanting to bring this topic up myself, as it has become rather annoying. I haven't seen 'simplistic posts' on Muppet Central, or any discussion forum for that matter, until very recently. Back in my day...er I mean when I started to join discussion forums, we didn't have texting or Facebook. Now that we do have these advances (really not the term I want to use here, but hopefully you get my point), simplistic replies have become much more easier, and therefore much more common.
Maybe we should remind people the difference between "discuss" and "chat". I really don't mean to be rude to anybody who has a habit of "posting for posts sake". For all I know, maybe I'm barking up the wrong tree.
