I added a PayPal button to my sidebar way back when “everybody was doing it” even though I know there won’t be any celebrities wandering by here looking for something to do with all that money that they can’t possibly spend. A button that would make sense would be a “cup of coffee” button. If bloggers were as close together physically as we feel psychologically, we would certainly take a break and share a cup of coffee together in the real world. Starbucks has gift cards that you can personally design. Why don’t they allow people to add a credit to each others’ cards? The technology is already available. Other companies do it. Maybe if enough of us asked, they would.
