Most of my best jobs came from LI leads, so I don't really get the point. I find LI to be a more open and just system than hiring a guy that knows a guy, or forcing people into slavery in open source.

It's not the hiring that is broken, but the tech industry itself. There is nothing that compares in how low a measurable value is priced in any other domain. It seems that the less you can put a price on something, the more people speculate that it is worth. There is probably some fancy economical law to follow, idk.
