I think I agree with you. I am an introvert, but have vast variety of interest in science, technology, startups etc. I don't like at all to do small talk with friends, i get bored and tired really fast, unless the topic hits one of these areas. I liked to socialize on forums on programming, and made a bunch of friends sincr when i was in middle school or high school that way. I gave a bunch of talks and raised enthusiasm on some programming concepts back in the day. Everything else was too boring.

I'm an extrovert, and I am also interested in "science" and "technology" (but not startups). One of my primary hobbies is very math-heavy, and involves hours and sometimes days of intense focus. I also gave talks in the past, e.g. on functional programming.

The point is, I have no idea how any of this is related to being introvert or extrovert (and was wondering the same in the post you replied to).

People can shut themselves into their room with only oscilloscopes and MATLAB as company on one weekend, and meet up with friends on the next one.
