This is just another one from Goolge, and its called 'Google Shared Stuff'…
Seems like just another social bookmarking, like Digg, del.icio.us, etc. Its not officially announced yet and still in the days of biginning… Anyway I got a page crated for me here, For more details refer to http://www.google.com/s2/sharing/stuff or here.
Don't know much about it, but just giving it a try…
