I've never read Amazon's Dynamo paper. I've also never had the opportunity to work with Cassandra or SimpleDB, but when Amazon announced DynamoDB I thought it was time to take a little bit of time to learn what it was just in case it was super-useful. I thought I'd share a few of my findings.

Disclaimer: I'm completely new to this style of NoSQL system and may well in fact be misusing it in places. Feel free to give me some free education if I'm doing something horrendous below.
