The unfortunate thing is that all these add-on job board solutions don't really go any way towards fixing the problem.
With the greatest respect in the world; I don't see this being a lot different (though I would be overjoyed to be proven wrong! :)). Not for any other reason that it is not really GH's focus...
See; it would be really cool to see this integrated with GH proper. With payment mechanisms so you could write a spec, post an ad, get someone sign up, code the work and then collect the payment. That's the sort of job board you should do :)
For the "real world" there is a lot of work to do for programming jobs - most of the offerings work for big corps and mid/large startups. Smaller indie firms like the one I work for struggle to find good local talent and there is just no one catering for us. And that is a huge market (I know at least 10 firms with the same problem within about 5 miles of where I work - in a sleepy market town).
As for this being different, I don't think it is supposed to be. But I guess we will find out once it actually launches.
I'm not saying our new jobs site is the magic bullet, but it's an area of software development that we think is lacking, and there's a ton of things we'd like to build to help improve it. This is the first step.
