I hate ads. I use adblockers, anti-tracking software and no-script plugins. I think, there are better ways to earn money from a project, for example a pay-wall, like premium membership or additional support.
If you, however, really do want to host ads, take a look at the Napp-It site. I know the guy behind the product and he has some quite good experiences with steering clear of ad-networks. Instead, he collaborates with selected companies and keeps the ads on-topic. The ads there are actually interesting and relevant for people visiting the site. Usually, ad-blockers won't hide those ads either, so it's a win-win situation.
