Wow, that's a pretty presumptuous article. The OP somehow confuses "extroverted adventure seeker" with "awake". Maybe we're arguing semantics here, but in my experience these are some of the least awake people I know. In my conception, to be awake involves a lot of meditation, enough in fact that it affects your demeanor in ways that can make you come across as reserved, not really there, and even "asleep" to those with bubblier personalities.
Quite contrary to the OP, in my experience the true inner state of a person is one of the hardest things you can tease out, and it's very very easy to be mistaken. To claim that it's fairly easy to distinguished awakened people by way of some light questioning, well, that just seems to me rather hasty, if not even silly.
