That's simple. If you want to hire a $150k developer, you offer $150k. If you want to hire a $60k developer, you offer $60k. You then interview people untill you find somebody with the potential that you are looking for. For the employer, it doesn't change much. They just lose some negotiating power.

Now, from the employee point of view, all the trashy jobs are correctly marked, what will save a lot of his time. Also, he gets a small bonus in negotiation power.

If you are a great developer (say, you are better than 99% of them), just marking what jobs are not fit for you will reduce the time spent on getting a job by orders of magnitude. That's the difference between the job board being useless to being usefull. As a consequence, one can hope (not a certain thing) that great developers will flock into a system like this, so that would become the place to go to get great developers, and as a consequence all the great jobs go there.
