Ask HN: What is the HN for quantitative finance?

Both of those subreddits are actually pretty poor mediums for "serious" discussion about quantitative finance. There's been an uptick in cryptocurrencies on each lately, and the subreddits are mostly saturated with early-career, "rate my algo" and "how do I mean reversion" questions from beginners.

I'm exaggerating, but only slightly.

Not a news river exactly, but I also learn a lot from the Stack Overflow sites:

https://quant.stackexchange.com/

https://stats.stackexchange.com/

The NYC FinTech Meetup is also usually a good place to network:

For obvious reasons, there really isn't anything great out there for non-beginner stuff. http://www.nuclearphynance.com/default.aspx is probably the best out there but not very active. Very deep archives though.
