So, first off, is this a shameful attempt to get people to register? Yup (Isn't every contest?). Is there actually $600 in prize money to win? Yup. So you're wondering - what's the catch? There isn't one. Write a great blog that people will enjoy, and get people to vote on it (using digg/reddit/stumbleupon). More info, visit: http://www.yuniti.com/BlogContest
