I am a plumber, and help moderate some DIY plumbing forums. We do LOVE to hear feedback from the homeowners, but most of the time don't get it. Yes we love the ego boost, and the feedback improves the forum for everyone.....but I suggest just don't take it personal if the homeowner uses the info and goes on his merry way.
I have used THIS forum numerous times for personal projects at home. I do thank you all for the help I have received, and provide feedback most of the time!
