I saw mention of this new Adsense revenue source:
[
google.com...]
It's where a pop-over appears that makes you answer a question before you can read the rest of the page.
The Adsense information suggests that you control a lot of the popup's features (how often, how much text shows, which pages, etc... [I'm not really sure exactly what because I didn't sign up]).
My absolute first thoughts had to do with how it would degrade user experience.
Then I multiplied 5 cents (what you get paid, per SERoundtable) times the number of pages I serve per day. Wow.
I still didn't sign up. I've been bitten and burned by the money bug before.
