Ok I will give you a simple method to separate the 2 groups of nerds and hustlers. Now this is not fool proof, but is good for about 80% of the time.

If they approach you - Hustler.

If you HAVE to start the conversation - Nerd - you might have to restart it too.

Most nerds are so involved in tech that they do not spend time working on social skills.

Most hustlers skip the tech and refine their social skills.

So find some techie forums / meetup / events and start interacting.

Myself I can fake social for about 15 to 30 minutes, but then I am exhausted. And I could not hustle my way out of a paper bag.
