I just added follower api support:

api = Radiator::FollowerApi.new
response = api.get_followers('inertia', 0, 'blog', 100)
response.result.map(&:follower)
=> ["a11at",
 "abarefootpoet",
 "abit",
 "alexgr",
 "alexoz",
 "andressilvera",
 "applecrisp",
 "arrowj",
 "artificial",
 "ash",
 "ausbitbank",
 "beachbum",
 "ben99",
 "benadapt",
