It’s so that you can approve .Google and only .Google .

“Well actually…” I understand that some of the large companies are leveraging it to ease filtering for customers. No one wants to block all .com, but you can opt to unblock/block all of .microsoft or .google, that would be useful.

Third or fourth hand information, so I don’t know how far along any of these companies in implementing, but… It kinda feels like they’re trying to build a centralized version a la CompuServe or Prodigy or even AOL over the internet that a company can choose to connect to.
