Sounds like most people have an ad block extension (I couldn't see the ad either; had to use an alternative browser). Op (or whoever is advertising) paid for an Adwords ad. Unfortunately it's not original. People have done this before and the CPC can rack up although I'm sure they've set a low limit to avoid paying more than a few bucks per day just in case.

Keep in mind getting attention doesn't necessarily equate to success (nor does equal failing either). I guess it was worth the split test.

What ad?

Why do you assume everyone will see the same thing you see?

He is assuming because he's the only one targetting "paul graham" as a keyword aka its the only ad up.

Nothing there.

Nope, not seeing any ad here...
