This gem is in use in some production sites to provide backing for a Rails app using content from WordPress and PostLaunch (a Java based CMS), and has specific dependencies on Typhoeus, Nokogiri, and dalli, favorites we use at Solertium. It's in the early stages of being made into a general purpose tool -- cleanup, generalized tests (our site-specific ones are stripped from the gem) documentation, performance, and decoupling from dependencies.
