Because if by some chance a schlub at WotC has been assigned to go "check on the masses" because there's a question about a particular playtest data point that Jeremy et. al. needed further confirmation on that was not made clear enough in the survey responses... that schlub ain't gonna spend their day reading through an entire EN World forum post that's up to around 40 pages with the same three people bitching back and forth to each other reiterating the same exact points they made back on page 3. At that point, the schlub will say "Yeah, okay, I got it..." and those three people are just doing it to hear themselves talk.
