Well Ok 4 very active boys still at home is an expensive hobby I will grant you, but that is not the reason (kids number 1 and 2 are married and on their own!).
Keeping a website up with useful information for the betterment of mankind certainly has value. I suppose I could have charged for the information you will find tucked away in these pages but I am a fair capitalist at heart. What that means is I don’t believe in ripping off clients. Nor do I believe in using the power of government to keep competing sites from existing.
I believe in presenting a good deal of information and allowing my customers to judge for themselves what value I bring to their lives. They can donate what they feel is a fair exchange.
