It's all based on public data gathered using this: http://code.google.com/apis/socialgraph/docs/

You can always just edit your contacts on the original sites where the information came from and either wait for a recrawl or force a recrawl using: https://sgapi-recrawl.appspot.com/

Some of it is from people I've exchanged emails with over GMail, which shouldn't be public data, unless Google has leaked it out somehow.

Did you see this: http://www.google.com/support/websearch/bin/answer.py?hl=en&... especially the bit about the difference between Public and Private connections?

I'm sorry my point is that I don't want to see private connection results myself in addition to no one else seeing them.
