I think it is a great idea! In this age of "networking" with everyone having a facebook page, or my space, or even their own website it has probably become more common.

I think, for me, unless I represented a larger entity, I would go with a combo of personal/business, but that's just me.

A question, probably nit-picky. Is it, technically speaking, legitimate to use the clan crest on a business or personal card?
Not that one would get docked for it, but just curious.
