Vitalik twitted that he like crypto kitty, I think he want to test ETH network and now hope he regrets about that idea. My ETH still pending.
I think he's right to say that this thing has been a good thing for the blockchain of ethereum. Definitely it tested again its reliability and how it can be improved but the most positive thing form me is that it has shown that ethereum can be used for very different purposes and not only for the smartcontract
