Well, that would be even better if it didn't have to be attached to one persons name, but hacking the personal tag system would work well enough for most purposes
I agree with tng that it's a very interesting idea. I want to ruminate on it for some time. When it comes to things like this, I've found that they often become the kernel for something that reduces complexity, but adds functionality. I'd like to think about tags and users in general in light of something like this. Thanks for the idea.
It's a really interesting idea. It could both promote community groups and more quality content. It could also be used as a way to be a jerk to someone by not including them. There is a gated nature to it, but not totally since anyone could comment on it. Worth considering for sure.
