The most valuable aspect of this site to me is...TRUTH
I can't speak for anyone else, but there have been many times in the past when I have been disappointed by a corporations claims. A certain product may actually be "useful" in a certain application, but the advertising makes rediculous claims and then the majority of consumers are left with a deep frustration and a cynical outlook.
Anyone can pull out their Visa card and order a $10,000 wind-gen/charger/inverter, especially if the ACTUAL output meets their needs, but, if someone is handy (or wants to become handy) they can get truthful information here about the components that they might purchase, or which parts of an RE system they could build themselves, to save money if so inclined.
I still consider myself a guest, but I have saved a great deal of information from here on a disc (because of its obvious value), and I have promoted this site every chance I get. I think Tom is doing a great job under difficult circumstances (anyone who deals with the public will understand!)
Nothing in life is perfect, and the most useful (and dynamic) things seem to have a slightly messy nature. If that is the price that has to be paid for this level of value, then I say, so be it!
