A couple of days after Blogger introduced the Blogger NavBar for blogs hosted on blog*spot, they are now offering bloggers the chance to monetize their blogs with AdSense.

Previously, blog*spot blogs displayed AdSense ads along the top of the page, earning money for Blogger whenever an ad was clicked.
Now, Bloggers can sign up for a special AdSense Blogger account and take a cut of those profits themselves.

When AdSense launched initially, "personal sites" were excluded from the program, but this rule has been relaxed recently (Google did not object to me adding AdSense to this blog back in June, for example).
