Personally, I think DAO is a joke, from a certain point of view, it personally split the ETH, the emergence of ETH and ETC

That was not intended as a joke. It was a good experiment. But it failed due to a bug in the software implementation.

it was a joke... the biggest crowdfunding ever without proper auditing and testing... a joke.

That is right. In the future, all the program/codes need to be tested throughly on the testnet before they can be released on the main net.
