I asked a similar question before. My idea is to pool the results and share my findings with everyone thats interested.

So, if you've used adsense or other sites before - take the survey!

Thanks

A more general "how do you make money?" might be more interesting and relevant to startups since we're not all focussed on blogging (the actual survey you're linking to survey "can you really make money from blogging?" and lists external ad networks as the only options. Many startups make money by providing services directly to users.

Thanks for getting the ball rolling in any case, this is neat info to gather.
