I have been playing around with event machine for a couple of days now and have been trying to work out a basic (quick and ugly) example to understand how it could be used for simple applications.
Though my understanding of the subject is still very superficial here is a sample application that you could try to get yourself going. There are a lot of tutorials available for this and I guess this would be a good starting point
To get a quick idea of the working app try changing the value of the ‘timeline’ key in the tweet_fetcher file to :public.
Further bulletins as events warrant.
