Well-deserved in my opinion. His no-nonsense and unpretentious way of building products, often out in the open, should be a source of motivation for others who can come up with a dozen reasons why they shouldn't attempt to do X. His blog-posts and Tweets are not hustle-porn but just straight-up "works for me, I honestly don't care what you say". A quote that I recently read applies to him very much: "Pessimists sound smart, optimists make money". Pieter doesn't try to sound smart, after all what could possibly sound smarter than making this amount of revenue as a solo founder.
