Yes, but not exactly via "F? SF?" thread. My situation was a bit unusual, so I posted here on "Ask HN" separately, got in touch with a startup founder and worked for him for 9 months - it went great. During that time we also worked with another guy from HN for a few months - and he got in touch via "F? SF?" thread directly. So yes, it is possible to find work here on HN.
