When I noted the replacement of the AdSense with the NavBar, I got to one of my favorite forum and ask if that move will open up BlogSpot to AdSense! No response in my thread ;-( But this morning Blogger, tadam, open up BlogSpot to Adsense.
This is a very huge new market (more than 1 million blogspot users multiply by the number of pages of each blog = $$$)! Ok let me be conservative. If only 5% is eligible with each one at 10 pages for ads, it still give you half a million pages for ads placement.
