W. J. Henson. John W. Williams. James F. Ross. William B. Snidow. But, I find that the programs pay enough for my direct usage to pay for my monthly internet connection and the host for this website.
Payment is based on either hours of use or a percentage of revenue generated by the ads.
The best and first of these programs is All Advantage . You must be actively surfing the web to get paid for your time. Another of my favorites is Desktop Dollars . You are paid for any activity as long as the ad bar is running and you are connected to the internet. Most are at present sending no more than a few messages a week.
