While this forum has it's followers I would think it highly unlikely any posting on here that is unsubstantiated would affect the share value at all. Brokers don't have time nor inclination to follow any one stock enought to visit this kind of forum. Most likely majority of people visiting are individual investors looking for more in depth knowledge about their investment.

Can't see shorters or day traders spending any time on this site. This forum is pretty much populated by long players. Some of us do take advantage of price moves to buy and sell but that's not why we're here.
