"But ads can get expensive, and many Web surfers simply refuse to click on them" ... Any guesstimates on how many?

It depends on the topic area.

We see click-thru rates
as high as 25% (1 click per 4 impressions)
and as low as .02% (1 click per 5000 impressions)

Ads for widgets get a lot of click thrus but widget ads get hardly any.
