I'll use a job board to find out who's hiring and then work directly, eliminating the job board. I leave my resume up on line whether looking or not though, I always get interesting offers and you never know when one will open a new door. Personally I think job boards are a waste of time though, the ratios simply do not support the effort.

If I was actively seeking work, a job board would just be another tool in the box, I find it so much easier, a lot faster and results in better salary to hunt direct and skip ads, job boards etc.

Nothing beats calling the employer (not HR) directly and asking for work.
