I just learned about this alternative to PayPal donations for websites. It is still PayPal, but in this instance the person donating receives a link on the site temporarily. As more people donate the link gets bumped down and off the list. It may conceivably work better than ads for webmasters (more direct). It also is a way to have more control over whose site you advertise on. It is simple to add to your site.
My TopSpots Widget is set for the minimum $1.oo.
