Hi folks, I thought this list might find a case study interesting. Urban Airship just released a new product, Connect, that uses Kafka heavily. We released some discussion of the why and how we built it at https://www.urbanairship.com/blog/why-we-built-urban-airship-connect and https://www.urbanairship.com/blog/how-we-built-urban-airship-connect respectively. The posts aren't hugely in depth engineering wise, but I hope folks find them interesting.
