Personally, I have hope that if a larger variety of people are posting and commenting (typical lurkers and such) then hopefully the echo chamber aggression will weaken a little, and hopefully foster a positive and friendly community. I'm trying to lead by example :)
You aren't entirely wrong, but I feel it could help build an appearance of high activity, which would help attract people. Also; many people wish to contribute but stifle the words before they can come out of their mouth, and I'm hoping a post like this could be the push they needed.
