Also Steve, if I may:
This is a very valid point, especially here. People who really know and really can provide good factual information are not going to risk what we here would probably consider a dream job to post. There are of course exception to the rule, but in general those exceptions are also forthcoming with the limitations of their knowledge.
Being skeptical is a very, very, good thing on an internet board. I think with a little bit of research, some well thought-out, well targeted post, and a smattering of half-truths, anyone can pop on here and make us think they have influence and information they don't, all the while never providing any real information.
I'll be honest, everything on the internet is a lie.
