I stumbled upon this fantastic website the other day, and felt that I had to share it.  Biblionasium is a social networking site created specifically for elementary-aged kids and the books they are reading.  The website has a great about section to explain how their reading program works, safety features, and all the ways parents, teachers, and students can use it.

It looks to me that teachers need to create a class list before kids can log on, so it may be too late to use it this year.  However, it’s definitely worth taking a look at!
