I&#x27;ve followed his site for awhile, and he seems like a thoughtful person who likes to document his reasoning.  I&#x27;m not a sysadmin, so I don&#x27;t care about a lot of what he writes, but he&#x27;s worth reading for stuff I care about.  For example, he&#x27;s pretty astute about the &quot;how&quot; and &quot;why&quot; of spam.
