Now that Video is no longer sharing space with Audio, there's no need to distinguish a question as being about either with a tag. Hence:
... is basically now a useless meta tag, since every question on the site should conceivably be about video, minus any that were missed during the migration period. It should be able to be burninated rather easily, but there are some cases where it's the only tag, so a glance through them would be extremely helpful if you've got some time.
That brings us to no longer need to differentiate between audio and video recording as well, which means:
video-recording could conceivably just become [recording], but I don't see the harm in leaving it the way it is. As the system applies popular tags to the HTML
<title> element, keeping it as it is might be better for SEO.
Thoughts? This is (fortunately) the bulk of the post-migration cleanup.
