First of all, please pardon my ignorance, especially those who are in this particular business.
I don't understand why people want to advertise on pixel advertising websites. First of all, there are tons of competitions among pixel advertisers. Even if people visit that particular website, how big do you expect the chance of that traffic to click on your website. You post a tiny, weeny jpeg image that nobody can see. Plus, there are tens or even hundreds of tiny, weeny jpeg images sorrounding yours.
If anybody knows the advantage of buying pixel, please do let me know. I might want to advertise my website too, if I see the advantage.
