Get Yourself a SugarMama -- Free Talktime from Virgin Mobile

This one's only for people in the U.S., and only if they're using, or are willing to use, Virgin Mobile as their cellphone service. Virgin have launched a new (well, it's new to me anyway) service called SugarMama that lets you earn free talktime in exchange for viewing ads, doing surveys, answer questions via SMS, etc. SugarMama will reward members with up to 75 free minutes per month. Apparently they've already signed up Microsoft XBox and Pepsi as advertisers.

As one pointed out to the NY Times, it may well turn out that this sort of thing doesn't really work well for advertisers. In many cases, people who will watch ads to earn free minutes probably aren't the most likely candidates to shell out for the latest Xbox. But I guess we'll just have to wait and see.
