Luboš and Mark Zuckerberg are both Harvard dropouts. Zuckerberg dropped out as a Sophomore when he got a zillion dollar idea. Lumo dropped out of the professorate for some other kind of reason. Like many who have actually earned a doctorate, Luboš is none too thrilled when rich guys like Z get one for just being rich. What really annoys him though, is that Zuckerberg said something about climate that conflicted with the Lumonator's climate delusions.
