You mentioned Twitter uses server sent events. Do you have a link you car share about that? I'm interested in learning more about how they use SSE.

One interesting use case to look at would be Marathon Event Bus: https://mesosphere.github.io/marathon/docs/event-bus.html.

One case I've come across them using it for is delivering updates for visible tweets in a timeline (e.g. like/retweet counts being mutated).
