I use the adbar for the top of all my blogs from
PlugRush. It does not fuck with my surfers, and the money from the adbar alone more than covers my hosting bills and some extra coin for new domains, link spots etc. I dont fuck with the mobile redirect shit, too many problems from other webmasters to risk using on my domains and getting fucked by Google. Whatever ad networks you use don't put too many popups and shit to piss off your surfers.
