It seems Google’s decided to dive into the arena of social bookmarking with their soft launch of Shared Stuff.
Simply add a bookmark button to your browser:
You can then use that to share your favorite web page. Or by clicking on any page that displays the share button:
From there you decide on a label for the page you are sharing, email to a friend, or push to other social bookmarking sites.
A pretty cool feature is that Google will auto-pick an image from the site, to use as a thumbnail. Users can scroll through the different images on the page and select an image that will best represent the site being shared.
