I don't know Job personally, but he did ref my first meet last May here in KY. He seemed a bit of an elitist, but I don't have much to back that up.
I don't know much about NASA other than what I've done. The teen division isn't large or competitive nationwide. However, I think their small meets are fun and worth doing if you haven't done anything else. Be wary, though. The rules are a bit tight. It doesn't impact me much though.
