Personally, I like the Corners Are Best section; I think it lags behind in posts because there are more drag racers here than road racers, but there's been stuff in there that was either useful or an opportunity to pass on some knowledge.

The bigger problem I think is two-fold:
1. Checking egos & superiority at the door.
2. Some folks wanting others to do all their research for them, and I don't mean exotic stuff but things that are already Archived here. That can be difficult to criticize, as I've missed or brain-farted some things myself.

Not everyone was raised by a mechanical engineer or Chrysler employee, nor were they trained to be objective and civil; everyone can learn the former, and should correct the latter, as the shoe fits.
