So, hey, I do this for a living and I figured I’d heard it all, by now, you know? All the tips, tricks, and hints about how to get ahead in the job search.

So I was pleasantly surprised when I was reading through TheLaddersNews Twitter feed — it’s put together by some of my very inquisitive and very insightful colleagues — Lisa Odierno, Jessica Carroll and John Hazard — and found a wealth of good new stuff.

Last Thursday, they tweeted this:

“Count the dollar and percent signs on your resume. Are you proving your potential ROI to employers?”

And I was struck by what good, common sense advice that was. I’d never thought of that one before and it makes perfect sense that counting up the $ signs and % signs would be a good indicator for how well you’re showing “ROI” on hiring you. That’s pretty clever.

It turns out that this quintet is regularly cranking out good job search information via Twitter. Here are a few other good ones:

@TheLaddersNews: Lunch interview tips: How to choose the restaurant, and order a plate without getting flustered http://bit.ly/apElT4

@TheLaddersNews: Jobless rates drop in half of metropolitan areas http://bit.ly/dvPCB5 via @Reuters

@TheLaddersNews: You don’t need to be gregarious to network well. Introverts, use your temperament to your advantage http://bit.ly/cRcPTW

And there’s much, much more over at TheLaddersNews Twitter feed.

It just goes to show you: whatever your area of expertise, there’s always more to learn, and you’ll find it in the most unlikely places — including right under your nose!

So many thanks to my very talented colleagues, and good luck to all of you this week on your job search!
