Wow CL101, Just when I was thinking you had taken a well-deserved break, you drop a mega-post on M&A.. Thanks, looking forward to digging through it in more detail this weekend.
Meanwhile, off-topic, I'm a big fan of Salman Khan/Khan academy from a home school year with my son years ago. His humble approach to online teaching single-handledly out-performed major online initiatives by M.I.T for example and other big institutions. He's big time now, but in the early days he aligned with your own simply stated interest in sharing information. Khan defected from the hedge fund world, I recall, and reclaimed his soul with free, global, education. Thanks for linking him here.
Best to you
