So, apparently, Contextweb/Pulsepoint no longer does business with forum sites. I put OpenX ads back up after being away from them for a few years, and... while it's only been a few days, I'm unimpressed with the fill rates. Does anybody have suggestions for other ad networks they've been happy with? We're already running Adsense as a remnant, mainly looking for a network that offers high(er) CPM campaigns. We aren't really in a market that does well with direct ad sales, and we're only doing about 1MM impressions/mo, which doesn't put us in range of a lot of the bigger networks. Suggestions?
