Somewhat off topic, but mongo recently came up in a design discussion. Some of the points here are intereting to consider/evaluate against the most recent version. My question is, given Mongo and the other NoSQL solutions, has anyone come up with a comparison of strong and weak points across different application types? Feature lists really aren't always useful - as noted about things like code maturity, etc.
