I do some reading up on the google help forums where people post there sites. A lot of the time they will post there site and talk about how they have no idea why they were effected by panda and what not.
Most of the time you will check their site and you will see a blog or the usual article site. You click on one of there stories and right above the actual article is a huge adsense block ad thrown in your face. This clearly says "click on my ads" and not "read my article". I think this is the perfect example of intent.
If your site is focused on trying to get people to click on your ads, you are likely to be pandalised. If the focus of your site is to get people to read your article then that is exactly the kind of signal google is favoring.
Of course not all sites that were hit by panda have ads. This is however a very strong factor, as if I were in charge of finding content quality signals is something I would take a good hard look at.
