Yes, I've used the feature--I spend a lot of time every day using Github. At my office, where I have a fast connection, it works very well and I like it. At home, where I have a shitty connection, it's hardly faster than the old method. I'm just pointing out that since they've changed the arrangement (e.g. no page reload when navigating between directories), they could take advantage of it to get a huge performance gain rather than a small performance gain.
