William F. Buckley has died

Here is one account.  I never considered myself a Buckleyite conservative but as a kid I was much taken by his show Firing Line.  It is the first time I was exposed to Hayek (I recall that Buckley blew apart his critique of social justice with a single question), or for that matter Milton Friedman, or for that matter Johann Sebastian Bach.  Here are many obituaries.  Here is lots of YouTube, recommended.

Addendum: Here is Ilya Somin on Buckley.
