Clojure is new. Hickey's status as the designer of a major and taken-seriously programming language is new. My knowledge of Rich Hickey is itself new -- I started seeing articles about the guy about a year ago. New means that most of the things that will eventually be written about Hickey and Clojure have not yet been written. Clojure has a future, but Wikipedia is about the present.<p>The current Wikipedia article on Rich Hickey doesn't actually tell me a whole lot about him. He invented Clojure, he's a software developer (logical consequence of the preceding), he "has worked on scheduling systems, broadcast automation, audio analysis and fingerprinting, database design, yield management, exit poll systems, and machine listening." -- where? how? with whom? All of these are <i>potentially</i> notable, but none are when they're shotgunned at the reader.<p>Of the sources there, <i>Code Quarterly</i> might qualify as a respectable publication, if it takes off -- it <i>too</i> is new.<p>Keep in mind that, say, moot, inventor of 4chan (more famous than Clojure) didn't have his own Wikipedia article until he started Canvas. Until as recently as June 2011, <a href="http://en.wikipedia.org/wiki/Christopher_Poole" rel="nofollow">http://en.wikipedia.org/wiki/Christopher_Poole</a> redirected to <a href="http://en.wikipedia.org/wiki/4chan" rel="nofollow">http://en.wikipedia.org/wiki/4chan</a> and it was only moot's ascendance as an entrepreneur which changed that. Wikipedia notability relies on secondary source coverage, and secondary source coverage requires time to occur.
