I went to http://www.google.com/dashboard to look at all my Google accounts and see what kind of information is leaking out. Answer: nothing.
I don't see what all the hullabaloo about the "new" Google privacy thing is about. If anything, Google has improved the way they handle privacy concerns. It's all quite transparent.
The only thing I objected to was that I found that I was unable to delete my iGoogle setting -- I'd tried it at some point and Google has kept a record of it. But that's more aesthetic than anything private.
If only other web companies were this good and transparent. Kudos to Google for doing this.
