1. Sesame Street has been around for nearly 38 years, and through out the years, Sesame Street has always managed to keep up with the times as far as children's education is concerned; I mean sure, shows like Between the Lions, or Clifford the Big Red Dog may offer a variety, but if you ask me, they still can't ever muster up to Sesame Street.
2. I think it's an absolutely brilliant idea, kids ALWAYS manage to pick up just about everything from what they see on TV, so when you have this tool that can teach young children while at the same time entertain them, I think that right there is just plain genius.
