How much productive time is lost to Facebook?

[Drew]

According to many experts Facebook gives many people the sense that they are actually accomplishing something. It could theoretically be used to constructive ends, but how much of it is just trivial thumb twiddling?

Too much. Hence the reason I don't have a Facebook.

As unscientific as the answer may be it is also the most accurate: "WAY too much time is wasted on Facebook". I don't know how some companies stay in business...seriously. Mostly people talking about how rotten their job is or how hard they're forced to work. I've told several folks that they should never write anything on Facebook they don't want their boss reading. That goes for spouse, in laws, mother, etc.
Way too much time is wasted on Facebook...and don't even get me started on Twitter!
