TechTV only became available to me a couple years ago.  The ScreenSavers was on of the shows I watched and these are the feeds I monitor of those that were on the show.  I would like to keep up with Patrick Norton, but I do not think he is blogging.  Still have to do some digging for a few others like Yoshi.
