I just read The Nature of Lisp on defmacro.org, which attempts to explain why Lisp is so rad. I have to say, it's by far the best article I've read in a while. I actually feel smarter, which is not a common feeling for me after reading anything related to Lisp.
As it turned out, the above article was a good lead-in to Sahil Malik's series describing some of the good new features C# 3.0 will have. C# will definitely be getting some sweet features previously only really seen in dynamic languages (to my knowledge) in the future. Can't wait.
