Google Photos blog informs that Google Buzz can now share private Picasa Web Albums: “It used to be all or nothing when it came to sharing a new Picasa Web Album in Buzz. If you created a public album in Picasa Web Albums, it created a public Google Buzz post. That was great for when you wanted to share your photos broadly. But for those times when you wanted to share with a smaller circle — no Buzz.
Now when you create a private album, the select people you choose to share your photo album with will see a notification in Google Buzz as well.
Just make sure you’ve Picasa Web Album as one of your connected sites in Buzz to take advantage of this easy way to share your albums.”
Google Buzz also added two other important features: muting posts by source, so you can hide someone’s Twitter posts, Flickr photos or the posts from another source, and editing posts and comments from the mobile interface.
