This is my experience with ESFPs, and you guys tell me if this is how you are:
I find ESFPs love learning, and love intelligent conversations, but don't typically take the lead in such conversations, and tend to be drawn to people who are articulate. They can pick up a lot of information via context clues and body language, etc.; and enjoy the challenge that comes with it. I think people erroneously find ESFPs as being unintelligent, because being Se dom, they have an easier time acting on the moment than expressing their deeper thoughts, but we Ni-doms help draw that side out. Being Ni-users, at some point, then, ESFPs can be pretty deep thinkers, and appreciate people willing to discuss topics that they have deeper thoughts on.
Just some observations I've had on people I've known.
