For a client, I recently had to evaluate a number of Rails content management systems. For their specific needs, they chose Radiant because of its large plugin ecosystem and its relative maturity. I soon discovered that despite being the rails solution that best fit the project, it still lagged far behind wordpress and other similarly battle-hardened software. Most of the other options didn't fare better. Unless you need interoperability with Ruby libraries, need direct access to ActiveRe* datasources, or you have a well-defined, tightly-limited use case, I'd recommend going with wordpress or something equally mature.
