I didn't realize that "tapesponding" had become so widespread. I know of two very prominent homebrewers (one now a Silent Key) who exchanged tapes. When I learned of this I asked if those tapes (which would have been a real treasure) were still around. Sadly, they had been destroyed, as, I suspect, were most of the tapes mentioned in this video.
I sometimes think that some of the on-the-air conversations about tech topics really should be saved for posterity (most conversations clearly should NOT be saved!). The internet provides a great forum for this kind of preservation. This happens, but only very sporadically and mostly in the AM world.
Thanks to Hack-A-Day for alerting us to this.
