Pros do not find the time to waste energy upon internet-forums like you and I do.
I do, I am a full time working pro photographer, but I have a keen interest in dispelling photographic untruths and offering unbiased gear advice based on personal experience. I also seem to be printing more and more so spend more time at the computer which enables me to have a browser window open here. I don't post or look any other forums though I look at many photographers work and have another window open at Creative Live almost all the time.
One of my observations with pros is that many of them are good at what they do, and professional photography is a business with never ending niches, but many have no educational basis for teaching, indeed many do not understand even basic concepts like "lens compression", perspective, equivalence, crop factors, exposure square for flash and ambient balancing etc etc. In this day and age of easy access I truthfully wish there were some sort of standard, or grading, of educators, you can learn a huge amount of stuff from people that are actually doing something, be that techniques, inspiration, business practices, etc, and it is all valuable, but anybody speaking publicly should be much more aware of correct use of terminology and the impact their words can have.
Oh, and generally photographers outside interests are not photography, they spend too much time hanging out and posting on climbing, skiing, diving, hifi and cooking forums
