LinkedIn is the most amazing business node graph out there - for a professional person online it has everybody and uptodate. But there is a wafer thin business model if they played their hand brilliantly - and they play it like a drunk Captain Hook trying second dealing in Vegas.
I just hope that when / if it all collapses we can club together and transfer out the edge connections.
I suspect this only works for P/E ratios above one order of magnitude - when dealing with companies that obey laws of gravity other factors come in to play (I mean seriously 900x earnings. That's insane).
It's the edge case of low P/E and low profits that indicates a non-valuable biz model.
Logged into MySpace recently?
Could some professionals ask to be compensated for being on the network? Yes.
Have the professionals on linkedin realized the above? No.
Oh and I consider the spam I have to wade through to use it a nefarious purpose :-)
