It takes all sorts to make a world, and a fair selection of them are here on Mudcat.
I don't contribute to threads that don't appeal to me, threads that have been hijacked or started by paople with an axe to grind, or threads where the wit has degenerated, IMO anyway, and the thread deserves to die. I don't think I've contributed to the 'Your Caption' threads, but I've enjoyed the pictures.
On the other hand, I don't want the humourless people, or the super-sensitive, or the singleminded ones, to control the content of this artificial community.
So, I open and skim a lot of the BS threads, and take it more carefully if it looks promising. I examine the thread titles in the music section, and contribute if I can. I'm usually too late to help, with the time difference.

Joe, I appreciate that you have to read every post, in your capacity as moderator, and many will be tiresome to you. However, if the BS section wasn't there, then this would be a less interesting place for me and presumably some others, those who contribute mostly below the line, and if people are contributing, then they must be interested!
