I don't think he was being rude or anything, just giving a little friendly advice. Plus your signature is contradictory: you make a point to say it's an open forum, but then you tell people not to post unless it's what you want to read.
A quick look and you have half a dozen threads reporting "problems" with signal strength, but no actual problems with service disruption, just bouncing number of signal bars. These fluctuations can be caused by a myriad of things from solar flares, atmospheric conditions, interference from man-made devices, tower issues, unseen obstructions from natural objects, etc. You should have an idea by now that it's not a problem with your phone. As long as you can transmit data and make/receive calls, just ignore it because it's not a problem.
I'm not going to say don't post things you think are a problem, but just think how you make a device look bad repeatedly posting about the same issue when there is really nothing wrong.
