Looking into Radiant CMS and Riak

Riak is unique because it's a key-value store with the additional ability to put links between the things you store and perform MapReduce queries.  Sean Cribbs supports the users of this database, and he also works on Radiant CMS, which is the most popular Ruby on Rails-built content management system.  Cribbs was the lead developer on the project for the last two years.

Sean Cribbs is a developer advocate at Basho technologies, the company that created the NoSQL data store, Riak.  It helps developers scale out the database to many machines quite easily.  Cribbs helps Riak users by providing support and training.
