I got to thinking recently, is there any way to automatically add the "tagme" tag to pictures that have fewer than a certain number of tags? (Let's say fewer than 10 or 20 tags, because those are the thresholds for getting that little face when you're editing to change from sad red to "meh" yellow to happy green.)
I've seen plenty of pictures here that only have the Copyright/Character/Artist tags filled in. At least with it having a tagme, site users like myself would be able to find it and fill in any missing tags.
