Lol. Looks like it could happen, someone posted this on my forum today: http://www.magic4you.nu/forum2/viewtopic.php?t=8482
Not sure why people are so amazed by it. My first affiliate sale for a certain program was from someone clicking on an ad network ad (it was before any search engine had spidered the page).
Well I am not too amazed by the fact that networks could generate traffic, but its always different when it happens to yourself you know. I am not amazed that Google drives traffic, but I was very happy the first time it happend to me! Same this time when I saw feedback that someone actually used the links on my site. .... I guess you know what I mean?
