If you're using chimp in a rails app, watch out; their gems (mailchimp_fu and acts_as_mailchimp) are kind of crappy because: * They're all untested. * None of them support the concept of environments. If you run your test suite, it tries to call mailchimp over the wire which is super slow and doesn't work on offline. * Calls to chimp API are done synchronously an the AR after_save callback which kills performance. * There is no method of batch process synch between your app and chimp. I'm working on a gem that solves some of these problems at http://github.com/bradgessler/mailchimp/tree/master http://github.com/bradgessler/mailchimp/tree/master (this isn't even alpha yet) which should make chimp integration easier. If anybody is integrating their ruby/rails app with chimp and are finding those plugins I mentioned inadequate let me know and maybe we can solve this annoying problem.
