Organize by number of tags?

Posted under Tags

Does anyone know if there's a way to organize the posts by number of tags? Specifically, the ones with the least tags showing up first.

I'd imagine something like this would come in handy for finding all the posts that have hardly any tags, but aren't tagged as "tagme". Then users could easily fill in the missing tags for posts that so desperately need it.

That seems like a great function, I'm not sure how it could be done but I like it.

Something like "status:tags:1" like how we have status:deleted for example.

I beat up my search script with negative tags, for example "highres -tagme -loli -shota -nude -1girl -panties"
