Ask HN: Do You Use an Ad Server?

Hi HN,

For my startup, we are looking to use an ad server to manage the ads on our website. We are currently looking into OpenX and some other adservers but frankly we are noobs on the subject. So I am interested to hear your opinions on the matter.

Do you have any experience or recommandation to share ? (positives and negative ones)

Thank you very much!
