I am sure they count every single account opened, even if it was never used. Still, the actual number of users is probably still huge and that is a lot of potential customers, if they could just get a proper program going to tap that audience without pissing them off. I do like the implementation of our store products being shown on our Facebook profile.
Facebook is becoming the "internet" for a lot of users. The web used to be something that you used when you had to find something, or for general browsing, email etc. Facebook has got users hooked into their way of thinking. the www isn't for surfing and email, its for socializing with people and growing a mafia.
Its something we need to embrace. its never been easier to reach a target demographic.
I have heard great things about Facebook share buttons.
Yeah I was never keen on those share buttons, did the minimum asked, but Facebook is now too big to ignore and a solid Facebook integration should be planned in the future. I've been playing with their API every now and then. It keeps changing though, which is annoying.
