In an earlier announcement, I indicated that I planed to remove the meta-tags audio and sound. I've gone through these and added tags where I could when either tag was the only tag on a question, but I'm starting to reach the limits of my domain knowledge.
Also, I'm running into situations where I find tags that might fit, but are also not great tags, and will probably go soon after these do, which just leads to a circular problem :)
If you have some time and want to do something awesome for the site, go through the list of questions tagged with either audio or sound, and find a better, more descriptive tag to apply to these. You can remove the problematic tag in the process.
If none exists, or the existing tags you're turning up all seem equally horrible (they could conceivably fit any question on the site) - you can leave an answer here with a suggestion to create a new, better tag, and a link to the post where it could be applied. I'll be checking this pretty much daily to make sure good suggestions keep rolling along.
Thanks to all that want to help! When we're done, we'll be much better organized, and probably much better indexed when it comes to search engines.
