I don't know if this is relevant to anything but here goes. Sometimes when I post, I go back right away and edit it, the edits don't bump the post back to the top. I'm not trying to be a post whore, but if someone else is postng while I'm editing, they might miss out on the kernel of wisdom I just edited in. I don't know, maybe I'm taking my contributions too seriously. It's tough being the center of the universe!
