Hiring technical people - what HR are doing wrong and how to fix it.

Very good essay, not just on the specifics (many of which you'll be familiar with) and looking at the problem from both sides, but in this conclusion that getting it right is important now:

"[ Logic would dicate this would be an employer's market], [h]owever that doesn’t mean that employers don’t need to worry about making the advertisement attractive and descriptive. Actually, I’d say it’s the opposite – since I know that there will likely be hundreds of other applicants, I only send a resume in for jobs that I think I have a very good chance of getting. I’m sure I’ve skipped over good positions just because the description didn’t communicate that to me – and I’m sure I’m not alone.*"
