@Billare honestly, SEO is not my biggest concern. the word "usage" is still in the title of the site, after all, and there's no restriction on it being used as a word in questions. plus, as you suggested, I'm not against allowing
usage to be used judiciously, on questions for which the tag is actually meaningful. it hasn't been blacklisted, and no one is suggesting that it be blacklisted (unlike
words)
