Hi! I don't know what would be most fun.
I started on this guy a couple of months ago. Perhaps something people are willing to hack on https://github.com/wallymathieu/auctions-api-clojure Mostly it is in order to get a feeling for the language. I'm by no means any expert clojure dev. Though it would be neat to see how it looks to implement an API with a lot of the parts you would expect from a real api (and some of the parts missing).
What are your thoughts @kongeor ?
