Just to be clear... you can go ad-free for 99 cents a month, not $99. I also use the free version of PB, but to tell you the truth the ads don't bother me in the least. I don't even notice them... I just don't pay any attention to them at all. But if those ads are helping to keep PB free for me, I say keep on running them. After all, they can run them, but they can't force me to pay any attention to them.
