NoSQL trends: MongoDB, Cassandra, Couch & Riak

NoSQL has been a pretty hot topic over the last few years.

But how are they doing overall? I've been meaning to build a NoSQL database trends report over the past few weeks. Today I finally got around to building a simple report on Google trends. Here are the results.
