The Yelp Effect

I was planning to sleep at midnight. I was literally ready to pass out but had the sudden urge to start a Yelp account. Two hours later, I've got 12 reviews! I don't know what it is about Yelp that is so addicting, but now I see why any given restaurant has 400+ reviews. I used to think that Yelpers were complainers, but I'm finding myself mostly rating my favorite venues and eateries. This can't become a habit, and I'm starting to think that joining Yelp was a mishap. I should have been studying!
