An anonymous reader writes: Since the introduction of the tagging beta, a number of tags have appeared that would seem to have little or marginal use. In particular, 'haha' and 'defectivebydesign' seem to pop up regularly. What does the submission of such tags say about the readership of slashdot? Don't you think think that the usefulness of the tagging system can be compromised somewhat by readers' attempts to be humorous? By example, what are the more interesting (and possibly useless) tags that have been observed since the pilot started?
