So as part of a pet project I decided to write a Ruby client for the Technorati API. There are several available requests that can be made and each has it's own options to pass for things like the response format. I should mention there is also a Technorati-Ruby gem available that looks like it was written back in 2004 and weighs in at around 500 lines. Mine weighs in at 130 lines or so but doesn't provide a response parser.
