I've been thinking about Slashdot's "tags" beta test. I think the feature has a lot of potential to indicate the real essence of a given article, when used properly. One inhibitor to this is the prevalent use of useless tags like "yes", "no", and "maybe". Perhaps you'd like to consider implementing a site-wide filter to prevent these nonsense tags from being used?
Thanks for your consideration, and thanks for maintaining one of the Internet's great web sites!
