Tumblr won’t share, another good reason to keep your own blog

Let’s say that Tumblr, right now,  has 21 million blogs (give or take). And they get an investment of $100 million (at a valuation of $800 million). So each Tumblr blog, on average, has earned that team four dollars and seventy five cents (or a valuation of $38) in the investment.

I wonder if the Tumblrs will get their slice of the pie?
