When reviewing some suggested edits, I stumbled upon suggested content for the kinect-hacking tag-wiki. There are as of now 48 questions that have this tag. However, I would say there is no point in having it.
Those questions with the tag are equally well served by a kinect tag or a openni tag. The fact that you might be doing something out of the ordinary with a Kinect (related to programming of course..sheesh) should be part of your question. And I don't think this deserves a special tag.
In summary: Do we need the kinect-hacking tag? Should we remove (and perhaps burninate) it?
Update: As of this time, all the 48 tags were removed and replaced with appropriate tags where necessary in addition to other fixes needed.
