zadu (the ICQ meets Third Voice thing I posted about a while back, but which I can't point to because, for some reason, I continue to annoy by not posting my archives) has launched an "affiliate program," stretching the definition of affiliate to mean reciprical links: "All you need is the 'download zadu' button! In turn, we’ll arrange to feature your site on zadu for a certain amount of time, which will guide users back to you."
