The airliners.net discussion boards are usually a joke. 90% of the users there are immature teenagers who believe that their opinion is gospel truth.
Sadly though, it does tend to attract some pretty influential people, who get turned off (or worse still, driven off) by the squabbling kids.
One example was my dad, who heads up the Inflight Service department of an international airline. He once posted about the details of a codeshare agreement he personally had helped negotiate, only to be corrected by a 15 year old who had "heard" differently.
