I visited Clojure Exchange 2018 in London.
Since there was only one track and I attended all talks, it is easy to just refer to the schedule.
Interesting topics, that came up multiple times in different flavors where immutability, stories of building real life applications, music, java and clojure and the transition, clojure script, emacs and cider…
I did a lightning talk myself about Some Thoughts about Immutability and its Limits.
I have just visited Clojure Exchange. Since it had only one track, there is no point in listing which talks I have attended, since this can easily be seen on the web page of the conference.
It was interesting and there were many great talks and I also met great people among the other participants.
