Once a site has reached a certain point, tag creation is no longer really necessary. Most of the new tags created on Physics.SE are crap (synonyms, localized, metatag, etc). Looking at the number of tag blacklist requests on MSO, it seems that SO has a similar problem.
Unfortunately, sorting tags by newest doesn't quite cut it. The newest sort doesn't show all tags, just a page or two of the recent ones.
Could we get full pagination here? There are a bunch of tags that probably ought to be burninated on (the nonexistant) page 3 onwards.
I think this will greatly help tag cleanup by helping us nip bad tags in the bud.
