I like it! It's nice to have all the pertinent information in one easy, convenient place. My only gripe is that it's a little hard to find if you're using a phone, but that's the case for a lot of this site's features.
I read the first book in 8th grade and thought it was entertaining, but I had no interest in continuing after that. It baffles me how the series has kind of become this whole trans-media thing. I get that kids like it, but I can't understand why moms in their 40s would be into it, but I suppose moms reading books meant for teen girls is a whole 'nother can of worms.
