Generally, sites like these are the "pulse" of the fan following, the true fan/follwer with a little bit more insight than the casual fan. Fans on sites and networks with a large following of hardcore fans tend to be a microcosm of the overall thought process of a fan base.
The overall feel that I get from this site, in the short time that ive been here, is people want more talent around LBJ, preferably a pg, people seem frustrated yet cautiously optimistic with Ferry and the talent around Lebron. This site seems pleased with the direction of the franchise overall and is enjoying the ride, but wants to see the team take the next step to elite status.
You can even see it in the press, who often regurgitate stories and theories which come from sites like these. Stories break on sites like these within in minutes or hours, the press has to check, confirm and reconfirm before releasing on their site, or the next day in the paper.
Why wouldnt players, press and organizations check these sites?
