I don't "do" FB and I know there are many others who don't. It's kind of sad (and makes many angry) but many a vendor has started on ECF.....gone on to FB and left behind the people who got them started out.
I know it is their business and can market as they want (as it should be) but it also serves them right when they start losing business. Then they all of a sudden come back to promoting on ECF and expect the same results as they once had. Doesn't happen. I often wonder why once they find FB, they don't do both instead of pretty much just FB.
