I've also noticed that someone added the keyword 'length' to Perl Monks User Search. When I first saw it, it made sense. I was looking at someone's list of posts (chromatic's I think) and I noticed the keyword. But then I noticed that it was on my list of posts too, and I started thinking that someone had gone and added that keyword to a bunch of users. So I went to a new user's list of posts (none) and saw the same keyword. I realized that the keyword was part of the page, and not associated with a particular user. Is this a bug, a feature, or something so minor as to be ignored?
