This was posted by Google’s Shimrit Ben-Yair regarding some minor privacy tweaks. These are the kinds of little updates that need to be squared away before the site goes public, so it’s good to see them working on it.

Changing your public profile picture or scrapbook photos will no longer generate a public post to the stream, just to the people you have in your circles. So only people in your circles will engage in discussions about the photos you post.
Now I’d like to see them add a feature to mute shared posts when the different people share the same hot post over and over. Coming soon, I’m sure…
