Where is episode 4?  Are you continuing production of this show?  I really enjoyed the first three episodes.  They were a great way of learning something new without sitting through the standard webcast (still interesting, just not as fun)  I would really like to see more episodes like the first where you can see the thought process the developers go through to get to the final result.  The first episode felt like they were challanged and thinking for themselves, not just reading a script.
