I wouldn't have seen this, usually when I log on to TER, it is either straight to the reviews, or here, but if you notice it, the results are kind of interesting.

Out of 647 votes, 33% say they don't participate on discussion boards at all, and 32% say they do, but just to read and don't post.

Kind of makes you wonder how many 411's could get answered if some of these people would get off the sidelines and into the game!
