Turn your social network (and what many people consider a bad habit or even an addiction) into something positive and motivational: Twitter your way to weight loss!

Seriously, though, this Dennis guy is doing it and it sounds like a fun idea that (depending on your personality) could actually work. Sure, it's a gimmick but all it's really doing is giving you an excuse to do something you were spending time on already, plus it also makes you accountable to friends and family for your weight loss progress. What do you think?
