Why was the DAO abandoned? It seems like someone could just fix the bug, and run the sale again, expecting a lower valuation.
The idea is still good, right? A bug shouldn't end the whole project.

#24I think it makes a lot of sense to build a DNS system using contacts. Names can be auctioned off and given automatically to the highest bidder. It is also possible to set up a contract where you could trustlessly sell names. "Send $200 to an address and you will get the name". There is an auction like this in progress already, and you can participate now if you like http://ens.domains You could do even more interesti…
Who is being trusted to accurately report whether the borrower has paid? I have never understood how the "oracle" problem gets worked out in practice.

#25Porn? So much technology seems to eventually come to making pornography -er. How can blockchain be used here? (Okay, sure, there's the obvious crypto payments for illegal stuff; that's not at all what I'm talking about). Regular legal porn, how can blockchain add to that equation?

The amazing this about this particular application is that an oracle is not required at all. So it's completely automatic and trustless. The contract (think of it as a class in Java) has a single function which looks something like this: function acquire_name() { if (msg.value > $200) {self.registrar.transfer_ownership(self.domain_name, msg.sender);}}
registrar is a pointer to an instance of the domain registrar that keeps track of all names. Here's an actual implementation of the registrar: https://github.com/ethereum/ens/blob/master/contracts/HashRe...

The idea was that code-as-contract was clear, unambiguous to all participants, and obviated the need for human intervention to enforce correctly.

you are right. Just enter your full name after you hit the buy button.

How would ETH name service Domains be integrated with the browser or this is supposed to work only in onion Tor and Mist browsers Update fixed formatting
There is a Chrome extension that does this for you for IP addresses (I think). All ethereum wallets are also implementing support. You can make your Ethereum domain name point to anything you want. So instead of sending your transaction to a long hex string, you can send it to "johndoe.eth".

There are many teams building projects similar to the DAO right now (except much more thought out), for example https://www.reddit.com/r/MakerDAO/. In the future, we will definitely see more DAOs - read this article if you're interested https://blog.ethereum.org/2014/05/06/daos-dacs-das-and-more-...
The original DAO was just a preview and it was too early when the whole Ethereum ecosystem was young (and still is, it's less than 2 years old).
