Vocabulary - I had more (by quantity and complexity) earlier than other kids, and I've only increased the delta between Me and Average Person to this day. It's extremely rare that I come across a word I don't know, or can't intuit, the meaning of. Have to go back to Victorian novels to find obscure words, just for kicks.
I don't think I'm anything special on speed or comprehension, though.
Thanks for the fast reply! I might need to make a little badge system for the kids. Of course, they'll think it's fun for them, but it would really be for me to keep some type of tally. :-D
