Liked this simple but complete tutorial on making a Twitter-like service using a key-value DB
This is a good tutorial for people just learning on how to use a key-value store instead of a usual relational database. And this tutorial is great as demonstrating a fully working Web 2.0 service, including security. It is based on the new key-value store http://code.google.com/p/redis/ a non-volatile memcached-like store written in ANSI-C for Posix systems.
