I just noticed today that some people have been tagging their questions as <featured>. In a few case, this is a legitimate mistake where they meant to use <featured-image> or <featured-post>.
It's easy enough to go through and re-tag questions, but it's a bit annoying to have to do this. Is the "Featured" tab so misunderstood that people think they can throw their posts up there with a tag rather than a bounty?
I actually think it might be a good idea to ban use of <featured> as a tag altogether. Opinions?
