I've been coding Java/Python for 10+ years (C/C++ before that), and recently started on Clojure a few months ago. I'm having trouble grokking Clojure since I'm not a Lisp guy, but after stumbling around like a blind rat I find that Clojure's syntax is quite extraordinary. I hope Clojure will become more mainstream as more people use them, and creates more tutorials for a layman like me.
The idea had so much potential; the execution was flawed though. Too much time has passed and yet Diaspora has yet to make much of an impact on the social network scene. Perhaps it is time to give it a rest, and let some other social network ideas bloom.
