There is a fledgling Hacker-News-for-quants at http://quant.ly.

The site is still building critical mass, but most of the current users are experienced quants & HF traders. (Disclaimer: I launched the site)

I nearly launched quantly.com a year ago. Almost bought the .ly but held off on it. Surprising to see someone using the domain here.
