&gt; Your knowledge of the subject and willingness to explain it indicates to me that you&#x27;re valuable to the HN community.<p>You&#x27;re too charitable.  The truth is I&#x27;m unemployed at what feels to be a particularly bad time of the year to be unemployed (think of all the family and friends get-togethers… &quot;so, what do you do?&quot;), and I&#x27;m bludgeoning people on the internet with domain knowledge in some lame effort to stroke ego rather than facing a bleak job market for someone of my background.  It&#x27;s a harsh toke, but admitting it (even pseudononymously) is the only way I&#x27;m going to do anything about it.
