The very Web 2.0 savvy John Cho is at it again. He’s got more great historical pictures of Hawaii and its taro culture on his personal Facebook page. And he’s started to post about his breeding work on a separate Facebook page dedicated to Colocasia esculenta. ((How many other crop pages are there? I need to find out, but how?)) If you’re into taro in any way, you need to become John’s friend.
