Speaking as an advertiser, I would love nothing more than to have 10,000 economically pinched nerds see a banner ad for my service, as I target the price sensitive consumer.

My strategy with advertising is more to say "hey, look at me, I exist" Once you know I exist, the price differences between my competitors and I give you enough reason to research me a bit more, and perhaps give me a try. So personally, I care more about cost per impression than cost per click.

Heh. this is the second time I've suggested 'project wonderful' - but as an advertiser it meets my needs exactly, except that it seems to be more popular with the webcomic set than the 'nerd news' set.
