Asking questions on the newer stackexchange sites, such as this one, has been rather frustrating for me because the tags I would like to use are simply not there yet. For now, I have just forgone using those tags.
I propose that permissions to create tags be granted to more people. Perhaps using total rep across all sites (as seen in http://area51.stackexchange.com ) as an alternative means of obtaining those permissions.
This suggestion of course has far broader implications than just tags, so comments and alternative ideas are welcome!
