I saw a great piece on Mashable yesterday that begs the question: How many calories do you burn while using Twitter?  Want to find out? Check out a fun Twitter application called TweetCalories, which shows how many calories you burned over the last 24 hours by Tweeting.

I didn’t Tweet too much over the weekend, so I only scorched a measly 2.06 calories. I think you burn more calories sneezing. I might Google that. Furthermore, this isn’t actually meant to be a top-notch weight-loss tool, but rather, it’s a marketing trick for a fitness center in Brazil.  I happen to think this is a cute technique though, not to mention somewhat successful on the viral side of things.  I mean, they got me to blog about it, right?
