Fascinating as always! Quick comment - the avg number of comments per posts is a bit misleading IMHO because there are TONS of posts (ie, from newbies without many followers) that get no comments or maybe 1 or 2 tops...then there are the posts from Whales that will get 20, 30, 50 ....or more comments. There's such a disparity there it's hard to really say what the "average" is. Just my 2 cents!
