This is a thread to connect rationalists who are learning the same thing, so they can cooperate.
The "learning" doesn't necessarily mean "I am reading a textbook / learning an online course right now". It can be something you are interested in long-term, and still want to learn more.
Rules:
Top-level comments contain only the topic to learn. (Plus one comment for "meta" debate.) Only one topic per comment, for easier search. Try to find a reasonable level of specificity: too narrow topic means less people; too wide topic means more people who actually are interested in something different than you are.
Use the second-level comments if you are learning that topic. (Or if you are going to learn it now, not merely in the far future.) Technically, "me too" is okay in this thread, but providing more info is probably more useful. For example: What are you focusing on? What learning materials you use? What is your goal?
Third- and deeper-level comments, that's debate as usual.
There may be some other online dating site that's more popular there. Here in Italy there are very few people on OkC, nearly none of whom outside major cities, and most of whom foreigners only staying in Italy one or two semesters, but Badoo is much more popular.
(BTW, this week I am in Germany, and it looks like all advertising on all web pages and Android apps thinks I should try out Lovoo (never mind I'm already in a monogamous relationship, and never mind I'm leaving tomorrow anyway), so you might want to check that out.)
I know of some other platforms and tried one for a short time. I liked the OKC approach and bet on that. Maybe I'll try other later. But Lovoo really looks like the wrong audience.
