I work for a company where about 1/3 of our revenue is from ads... it's pay per view, not pay per click for most.. some direct-sold campaigns which tend to do better than the ad networks.. most well targeted. I personally don't like them, and would love to see a 2-ads per page limit.. (including services ads)...
Most of the direct campaigns are actually well targeted to our users. Products/Services that are useful, and likely to be used by those using our site.
I don't have a problem with targeted/useful ads... Hell, lots the posts in HN could be considered advertorials, just the same, I appreciate knowing about more... Where my problem is, I don't like highly intrusive ads, or far too many ads.
