Domo, I think it is nice that you realized it might bother some and asked.
I don't think of you as a troll---trolls try to stir up trouble, and I've never felt that about you.
I do, as others have said, find it annoying that often half a dozen threads or more on the first page are just silly jokes by you. And mostly I skip right past your threads. I also find it a bit annoying that sometimes the titles sound like there will be a real discussion or question, so then I open it and see, shoot, another dippy joke. I know it is meant in harmless fun, but it comes across as sort of "look at me" and "these are the Domo boards" sometimes, wich is not a huge big deal, but results in an eyeroll from me.
I really like Allison's idea of make one "Domo jokes" thread----it would likely stay on the first page or two most of the time, but not dominate the page. People looking for light jokes would know where to click and people wanting to be involved in discussions wouldn't get annoyed at clicking on what they think is a real issue or question only to find a joke. Heck, I'd be more likely to read your jokes myself once in a while if allowing one thread to load would let me read many, and if I wasn't sick of seeing all the threads.
