We all know about tagging on Flickr and del.icio.us, and we also know of how it’s being used in some fringier sites like Consumating or Dinnerbuzz.

My question: are tagging and folksonomies occurring in more mundane enterprises? In an essay I wrote, I imagined a tagging interface for an intranet. Has that happened? Gene has told me of how he developed tagging for an internal employee directory (where you could tag your skills), but that’s pretty much the only mundane example of heard of.

Anyway, please post comments if you’re familiar with tagging and folksonomies in less fringe-y web use.
