Hmmm, I wonder what @richhickey's going to talk about? (here, via @fogus) -- It looks like Rich Hickey will talk about "something new" for the NYC's clojure meetup. What will that be? My vote is for Forjure, a Forth implementation for the JVM ;)
A programmer has a problem. They decide to use #Clojure. Now they have a WORKING ONE LINE SOLUTION! (via @myfreeweb) -- Clojure, the language for tweets.
ReadWriteHack: 10+ Free Resources for Learning Clojure (here, via @rww) -- As Clojure is becoming mainstream, judging from how far removed is ReadWriteWeb from hard-core language geekery.
Automatoon: A HTML5 automation service on GAE written in clojure (here, via @hnfirehose) -- This is built with CoffeeScript on the front end and Clojure on the backend.

It's author also wrote "Land of Lisp".
Bitly API via Clojure (here, via @gmwils) -- Short and sweet, use Bitly's API to shorten your links from clojure.
