It's interesting you should bring this up I've recently been wondering about this as well.

How do you find other people who just love to learn and master things. I agree that the best place I've found so far is hacker news, though it feels more that it just happens to be that way.

I would love more spaces like this by the way. Many people seem actively hostile towards learning.

Speaking of spaces if you have a local hacker space around that might be a good place to look.
