Not necessarily idiots, If you are expecting someone going through and throwing out resumes to be happy that you know X languages worked on X open source projects think again.. That should be left to the person interviewing and hiring you.

To be hired you have to be able to stand out of the croud while fitting into what is required. HR is there to make sure the latter is true and once that is met see if you have shown enough to move up to the next level.

You've given a nice description of how pathetically little value HR adds.

That's an idiotic job, as you described it -- and really only makes my point for me.
