I started using job boards back in the days when Dice was a dial-up BBS that I had to call using the local library. And Dice helped me get the job back "home" in Houston that enabled me to get married. In the go-go days of Tech Boom 1.0 I got several jobs via boards like Monster. People were hiring computer talent sight unseen.

And the boards are still helpful for me today. But you're NEVER going to get free doughnuts and a unicorn ride just by posting on a job board.
