For those of you not hip to the fun and exciting world of alternative holidays, today is National Cheeseburger Day. Certainly a holiday this foodie can get behind.

It's also a holiday Kraft is getting behind - and for the greater good. In honor of National Cheeseburger Day, check-in on Foursquare at any Five Guys Burger & Fries and Kraft will make a donation to Feeding America, a non-profit that runs food banks across the country.

The promotion is lasting longer than the one-day holiday. Just connect your Foursquare account to Kraft online and your check-in at Five Guys over the next two weeks will count toward the charity.

This is yet another good example of linking location-based networks to cause marketing, something that has been taking hold on Foursquare and SCVNGR this year. BFG has been working with Auntie Anne's this fall on a SCVNGR-based promotion with proceeds going to Alex's Lemonade Stand, an organization that fights childhood cancer.
