That's because it's not 100% clear, even to us. Think of it a bit like a bunch of people pulling stuff out of a burning building. [0] We know there's more to be saved, because we can see more boxes in the building, but we haven't taken the time to see what's in the boxes we already have.

Yahoo aren't making this easier, either. (Blocking our efforts, unreliable servers, limiting what can be downloaded, providing incomplete archives, etc...)

Once the dust has settled we'll be able to start going through what was saved. There have been a lot of really interesting aspects to this project that I hadn't encountered before, and I hope to document them when I have the time.
