Forums are populated by people, and where there are people there will always be problems. Like others have mentioned, try to ignore the bad and take what you can from the good.
This is not directed at TBN specifically, but over the years I've found that while many people on forums are simply trying to be helpful, others seem to take some sort of perverse pleasure from trying to get a rise out of people, but if you ignore them you're denying them the very gratification they seek. Forums also seem to be magnets for know-it-alls who have to be the biggest/best/first at everything. It's all about status and reputation, where numbers matter more than substance. Life is just one big ...... contest, which is little more than a waste of time, but they never learn so it's best to simply ignore them entirely.
In my experience, it's all to common.
