Where can i actually help people with different projects that'd actually result in actual change, and where the people involved (at least one) is treating the project like, at minimum, a part-time job? As in, treats it seriously, is passionate about it, works on it regularly, and most importantly, WANTS TO TALK TO ME ABOUT IT. 

Anyone? Anywhere? I so desperately want it. If it helps, I make english-parsing AI.

Some ideas:
-Read holocaust stories, write down what's in them
-Make memes/etc about a SPECIFIC thing (example: reasons for Germany's actions in WW2)
-Pick any topic/issue, discuss it often, focusing on how to actually advance the issue online
