Distinguishing Our Voices?

One of the repeated comments we got in response to Episode 1 was that it was difficult at times to distinguish our voices from each other.  This was one of the reasons Episodes 2 and 3 were released in stereo, besides the usual mono.  The positional cue, I'm sure, make it much easier to tell us apart.  It proved too much of an extra time commitment to continue to release stereo versions, unfortunately, but my thought was always that our regular listeners would learn to distinguish us once they got used to listening to us.

Well now it's been 10 episodes, and I'm curious to know if that's true. Do any of you regular listeners still have trouble distinguishing our voices?
