I've never posted on the "Who wants to be hired" but I've applied to a number of positions on the "Who's Hiring" and consistently get feedback from those.

If you've been looking for a job for year without any promising job leads, i would recommend:

-seek some feedback on your resume -speak to some professional developers for some general advice on getting the first job

I'd be happy to help if you want to message me on twitter @jakeduchen
