I'm not one to read the news (not regular news anyway) but a relative came across this article today. In a nutshell, a woman has tripled her income by trusting customers to pay what they can afford. Now this doesn't mean her items are free, and she didn't re-invent the wheel. Ironically it's what most of us IMers do every day: Give free tips through our blogs and since most people never do anything with free information anyway, they pay us to do it for them. Netmoney1 had a good post on this exact ideology. It may not work for every business, and this article is more of a Case Study than anything. But the point we can all walk away with is by using friendly obligation (when someone does something for you, you generally feel terrible if you can't repay), you essentially force your customers to WANT to support you. Maybe this can envoke some creative uses of this tactic on the forum. After all, IM'ing is just a search for constantly changing loopholes.
