I don't like the idea of categories because they legitimize noise. Plenty of times, I've thought of one wise-ass remark or another, and I've not written it because I know very well it's a lousy contribution to a discussion. I might not have been so discrete, however, if I'd had the shelter of labeling it 'humor', and I think the site would have suffered for it.

Of course, I've gone ahead and posted some of my wise-ass remarks also. It sounds good to have those labeled, but I think I'd rather have less unlabeled noise than more noise—but with labels.
