I wouldn't stick with blogger. There's really no good way to monetize it as far as I know. Plugrush no longer accepts it, and I'm sure other networks have similar policies against free hosts.
Something you may want to look into though, is if blogger tracks views, or -unique- views. When I had a blogger account I'd get thousands of views a day, but I don't think they were unique views.
I'd recommend setting up a site with a real domain and host, and then forwarding the traffic from your blogger account to it.
You can do that by putting this code in the header:
Code:
<meta content='15;url=http://www.yoursitehere.com' http-equiv='refresh'/
The number in the code is the number of seconds you want it to wait before it forwards to the other site.
After that, go with
Plugrush or
Juicyads.
