Bias? We've heard of it
Yeah, I'll believe how much Facebook is totally contributing to economic growth when we get figures from someone who's not being paid by Facebook.
I can sort of see how FB, Twitter ect can be integrated into a company's existing customer interaction processes, but on the other hand I've seen various companies who seem to think a Facebook page is an adequate substitute for a dedicated webpage, and most of the time the quality of information available (or usually not available) tells me everything I need to know to decide that they're not getting my business....
