I'm sure Zuck and Sandberg went straight for the delete button on that email. "Oh its linkbait Calcanis ranting about something stupid and trolling for an Adviser gig."
Its so odd, I do really like JCal's stance on other issues (paid pitching groups) but his fb rants are annoying.
He should have wrote them a thank you letter for delivering an easy to use tool for exporting all content rather than just a simple PS mention.
