"as well as individual investors like ... Calvin Broadus Jr. AKA Snoop Dog [sic] (also randomly)"
Snoop Dogg is actually a pretty active reddit user: http://reddit.com/u/Here_Comes_The_King - especially in a certain..err.."plant-based" subreddit.
He's done several AMAs that are actually amazingly fun to read. In some ways, AMAs can provide a better "celeb-to-fan" interaction than Twitter so I can see why they got a few celebs in this round.
