I can make mistakes, we all do. I try to only post about stuff I have a clue about. Sometimes it's not right and I get corrected. Sometimes I correct people that have been on here a long time. It's the nature of forums, you learn as much as you share, and the more you share the more you will see ideas you had never thought about that may or may not apply. You have to be willing to be wrong, and not get too upset when people call you out on something.
The best thing to do is not follow users, but follow threads of interest and cross reference them if you can. That way you will have the best information possible.
