I saw the following video and thought it made some really good points. Is the guitar going the way of the banjo? When you hear guitar players in the shops, are they playing new music or the old standards? Are you hearing much new guitar music these days?

Just as a side note, I think guitar manufacturers would do themselves a favor if they focused more attention on designing guitars for smaller, female bodies or just guitars that had more appeal to women. That might help expand their market maybe even boost the direction of guitar music.
