Clojure is the most exciting environment I've used for years. I've spent most of this year learning to write and actually writing non-trivial programs in Clojure. It's been a fun ride, the best one for years!
With Clojure programming becomes, instead of fighting small but bugging issues with the system, following your curiosity instead.
I donated $100 so that Rich Hickey can continue working full-time to make Clojure even better. You should read more <a href=" http://clojure.org/funding ">here</a> and click the "donate" button at the bottom of that page.

Rich was spending way too much time on clojure, but he wasn't making a living at all out of it. Just from what Clojure has taught me on concurrency and time management, it's been worth every dollar. I wish I was a company and I could dip my hands into deeper pockets.
[EDIT: Rick/Rich ... there are too many Rick/Rich in my life. Thanks for the notice.]
