Finding a job is almost just as difficult as hiring, even if the person is credentialed and the company has many open positions. If you don't know exactly what you are looking for or what you may be good at, theres a good chance you might spin your wheels.

This is pretty common in the tech industry as I've come to realize. The issue is that many people can be good at programming, and hell, they might even have open source projects or even shipped applications to show for it. But put them in a software engineering interview where they have to walk through a basic dynamic programming or data structures problem and they will probably stumble. This situation is even more likely for interdisciplinary individuals where they don't have typical degrees for their field of interest.

So, point being, it takes a while to find a good fit. One where your skills expectations are agreeable for both sides. I don't see advertising on HN an issue, since we are the target market for this type of situation, but so long as it doesn't become a job board.
