Recently I've noticed an increase in very annoying pop up ads when navigating on yahoo. You don't even have to click on the ad, just have the cursor (accidently) move over the ad, and it pops up. If this continues, i will not use yahoo as much.
How much do you pay Yahoo each year? How many ads do you click on? How much do you buy from Yahoo's paying advertisers?
Assuming the answer in each case is zero, why should they care whether you "use" Yahoo as much?
