Hi JB-
I think anything that helps parents or teachers to better understand and work with gifted kids is great.  I like the idea of having a list of gifted blogs, though I suspect that Hoagie's may have such a list already.  Especially for newbie gifted parents, hearing true stories from other families can be very enlightening.  I think in part, that is why Ruf's book is so popular.  The case studies really speak to people.  I'm not entirely sold on her levels, but I did really enjoy reading about all the gifted children as individuals.  
good luck on your new venture!
