Andy is currently seeking contributors for the site, and I think this is definitely a worthwhile endeavor. Hopefully we can get in touch with some music education professors and those who have influence in the music education world to try to get more people on board.
I know a handful of musicians and music teachers are subscribed to my blog and I hope they will give Andy some encouragement, links, and just send people his way.
I also would like to add that he has chosen a very nice, minimalistic, and clean WordPress theme for the blog. Outstanding job!
