Not that it should be too surprising to me, but (even as a long time Rubyist) I'm finding the "Haskell":http://www.haskell.org/ posts on "Slick or Slack":http://slickorslack.com to be the most beautiful so far. When I took my first look at Haskell years ago, I thought it was ugly. Every progressive year it strikes me as more and more beautiful.
Why am I not a Haskell programmer, then? More on this in an upcoming post.
