I'm puzzled here, two of our biggest tags, with lots of followers, are user-behavior and user-interaction. They're pretty close to being intrinsic tags (applicable to the whole scope of the site). But since they're highly followed and frequently used I'm not sure about removing them.
What value do these tags provide and how should they be used? Should we keep them?
Think of it this way; tags should be able to stand on their own as the only tag on a question; that's one of the criteria for a meta tag; meta tags don't work on their own because they really don't meaningfully describe the problem space. Does a question tagged only "user behavior" really make sense? Or "user interaction"? Is there ever a question in either of these tags that wouldn't be better served with more specific tags like scrolling or click?
