There are things I would _really_ like from google - where I fit in to their adsense categories, for example. (I'm not sure whether this data is anonymised or not)

I just downloaded this data, all the data they would give me. I got my email address and my name back. I also got a handful of contacts. I consider myself a reasonably heavy google[-owned projects] user.

This, for the most part, is useless information.

What I would like is exactly what they would give to the government (obviously, after confirming fifty times that it's actually me they're giving it to).

Regardless of all that, I think this should boost Google's image. Very smart to focus on social privacy, when that's Facebook's one downfall.
