I used this site to gauge my future cost of living before moving to another country. Once I moved I noticed it was off a bit, but didn't think much of it. Then one day, while bragging about how cool this site was, I noticed that it does other things (crime index, health care index, etc), and when I looked I was shocked to see that it listed some very wonky crime stats. So I looked over everything and realized that a) it's all based on voluntarily submitted data, with no checks on anything; and b) the sample size was very very small. No wonder people thought my Western Canadian town had more crime than the Tenderloin, SF. The sample sizes (at the time) were 8 vs 6 Super awesome site but it needs 300x as much data before it'll be particularly accurate
