Some people don't want to wade through all of that.
Some people do. What a crazy world it is where people on a discussion board might want to discuss things instead of just a dry recitation of facts.
Here's where it becomes a problem for me, and not so much a problem for the forum. I have email notifications attached to this thread (and one or two others). It sucks to have to wade through extraneous crap via email, when all I really want is a show announcement. I don't care if you want to discuss the merits of the Pietasters vs We Were Promised Jetpacks anywhere else.
I get that you don't care if I get emails filled with your inane banter. You may actually enjoy it. But it makes me annoyed with you, or at least as angry as I can be at a random anonymous internet person. I could turn off notifications. I could leave the board all together. Or you could play by the rules.
