Ask HN: Good advertising network for a site with 4M views per month?
I've been running a site for quite a few years that now sees around 4 million page views per month. It's a large community site with discussions about software. I've only been running Google AdSense on it, since it was what I'd started with. But revenue is only around $2,000 a month. Based on some reading on HN, it seems I could be doing more with it, but I honestly have no idea where to start...
