Clojurians Log v2

Hello guys, as I was saying on #C03S1KBA2, together with LambdaX I would like to be your Cicero for a day

we are thinking about having a training at the beginning of may in SF

If you can help me with choosing the topic (put a 👍 on the line you like) it would be great

1) Parallelism/Concurrency: trasducers, pmap, core.async

2) The seq abstraction: seq, sequential, comparing Clojure's data structure implementation

3) Web: ring abstraction, compojure, comparison between web servers/web frameworks
