One of the funniest moments was when we were asking for help on how to use the Streaming API with CORS, so we wouldn't have to poll the API a shitload for our real-time demo. Our conversation with some app.net team members went like this:
< "Have you tried using 'eventsource'?"
> "Yes, we're using 'EventSource' but we can't get CORS to work."
< Look of confusion.
< "Can't you just use a Readable Stream with chunked encoding?"
> Look of confusion.
