I was reading through Milan Parmar's post on how to get paid by Google for user research studies and (surprisingly for me) clicked on the link for an application. (I'm not really into applying for things left and right; just consider that this blog already had more than 200 posts before I decided to step up things by applying for Entrecard, BlogRush (failed), BlogCatalog, Adsense, etc.)
The survey I took (just for the application) is worth it, even if my application would be denied. I was even surprised with my answers. For instance, I realized that I'm not really into photo sites like Flickr.com and PicasaWeb (I did not even know its URL until now :-)), and although I frequent YouTube, I don't know how to create even a simple movie. Surveys like this get you into thinking about your daily online habits :-)
EDIT: Here's a longer review.
