So, we now have the breaking-bad tag on Chemistry. The posts there aren't really bad ones, some, like this one, have really interesting answers. It also might be helping drive traffic to the site.
I've remarked before (in jest), that a things-I-won't-work-with or derek-lowe tag would be nice to have to keep track of the questions sprouting from Derek Lowe's blog series that has prompted a couple of posts on our site.
Appropriateness of these specific tags aside, in general how appropriate are tags that describe what sparked the question rather than what the question is about?
They seem to be a form of meta tag, but I'm not sure.
