Yes, I think the cryptokitty is a good way to prove the ETH network is good though there is some crowded situations. I also think it is a good way to Let more people know the value of ETH.
Honestly, it is and no matter how bad it was for the increase in gas fees, it was not as bad as if that would have been on the bitcoin network. So far, Ethereum has been doing its best, and what is being experienced is so little that can easily be solved in some little time later on, so I am still very optimistic with the Ethereum network, even though we have plenty of Kittens running around right now.
