I was doodling in code this weekend and the result is a small gem that hooks into the after_save callback to send model changes to a Twitter account.
Make sure you install the Twitter gem. Then in the demo app, update the config/alastrina.yml file with your Twitter credentials. Open a console and do:
a = Place.new a.name = "GGG" a.save
And, presto, the model changes should be posted to your Twitter feed.
