There's tons of humourous comments these days. When I first started here (well after the name change), if there was even a hint of comic intent in your comment, it'd be pounded deep into the gray, never mind anything like the comments you see now that are terminated with /s. I even used to have a screed against the extreme humourlessness of the site in my profile. In those days, the only way you could get away with making a lighthearted comment was to be a 'name' (like pg or other prominent users).
