If you have posted as a freelancer, have you received offers of work? Or, as an employer, have you found a freelancer you liked?
The most recent, for August, is at http://news.ycombinator.com/item?id=8120079
I run a consulting firm in Ohio (http://infincia.com). We build and maintain new and existing iOS and Mac apps, and create highly available server backends for them.
Everything from short term contract requests to full employment offers at well funded startups in SV have hit my work email address, specifically mentioning the freelancer thread in the initial conversation.
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.
