I have a wall of pictures of people I really, really like. They have different attributes that I value and they are very, very smart. You likely have never heard of any of them, unless you are heavily into electronics, computers, philosophy, libertarianism, or Mormonism, which says a lot about what fields of endeavor I pursue!
Here is one that is actually still living and is still incredibly productive (which is the attribute I treasure in him along with his staggering common sense) - DON LANCASTER!
This is a link to his "What's New" page, which looks suspiciously like a blog. He doesn't mind passing out his ideas and experience for free, which is also something I admire.
