Read Thread: Why am I seeing ads?
I kind of suspect the vast majority of people who read that page find it through a Google search. Since they aren't letterboxers and unlikely to ever become premium members, I figured I'd put ads on them. They can pay for using the site through that method. =)
And I figure it's not too onerous for AQ members because while most people will look at the tutorial at some point, it's not usually the kind of thing they go back to over and over again making it annoying.
And thus, the reason for the ads there... But they've literally been there since a couple of months after I started Atlas Quest!
I only see one small ad. Unobtrusive, and no photos or things that flash to distract.
