"People clicking have to buy something in the end"

I believe the ads above GMail are pretty lucrative... also people on webchat are often trying to buy something.

And that's not including the massive areas of non-tech IRC communities."Anyways, please don't take this as harsh."
hehe it's ok, I've been making money off online advertising since 1999. I'm 90% sure I know what I'm doing ;)
