I'm just curious if anyone really actively participates in this promotion because I'm trying it. But it seems like it would take an investment of my time just to figure out if I ever get anything besides "points" out of it. I remember when I first started getting credit cards. I signed up for a Sky Miles card because in my naivety I thought 5,000 free sky miles meant I could travel 5,000 air miles free. Uh uh. I think it bought one change of business class to first class on one flight.
So, I'm just wondering if it's even worth setting Bing as default search engine.
