Thanks very much for the kind words.  I have toyed with the idea of doing a regular podcast, definitely on retrocomputing, but it would be centered around the subject I know the most about, which would be old PC/DOS machines.  There are some video podcasts that cover this, but not a regular audio one dedicated to the broad hobby itself (the video ones are game-centric), so I think I might actually give it more thought and pursue it.  Thanks again.
