In looking at the questions, they pretty much all seem to belong on Meta. Can anybody think of a purpose served by this tag that's on-topic for SO?
Maybe if someone attempts to use it they can be notified that:
Hey, if you're asking a question about StackOverflow, why not hop over to http://meta.stackoverflow.com and join the discussions there?
New users are unlikely to even know about Meta, but this might help them along.
(That's more just thinking aloud, the actual request here is to nuke the tag.)
