But when you do a "git pull" you're not pulling from someplace identified by a hash, but rather a hostname. The learning-about-new-hashes part has to be handled differently. It's a legit limitation on what content addressing can do, but it's one we can overcome by just not having everything be content addressed. The web we have now is like if you did a `git pull` every time you opened a file. The web I'm proposing is like how we actually use git--periodically pulling new hashes as a separate action, but spending most of our time browsing content that we already have hashes for.
