The applications tag has suddenly been added to a lot of posts by an enthusiastic tagger. There are now over 400 questions. I didn't do an exhaustive review of these, but for the ones I looked at, this tag doesn't add anything useful (and I can't imagine how it might).

Perhaps if we start deleting it question by question, we'll discover a few cases where it either adds something or could be replaced by something more meaningful. My suggestion is to either start that process or just nuke it from 30,000 feet and save flooding the active questions list.
