I think you mean that it can be difficult for most companies to find qualified candidates, for example software developers. I've heard many people complain that they can't find good coders, or any coders at all in some cases.
Yes exactly - I got a little extreme on the 140 character cut off, but that is the idea. Everyone wants to hire great people, but the only surefire way to find them is to have worked with them in the past. I want to crowdsource this information to find out who the A Players really are. (Hint: they didn't all go to Harvard, integrate by parts, or explain why manhole covers are round.)
