Google started Shared Stuff for users to share links and other useful information with their friends back in September 2007 but now Google is shutting down the service because Google think that only very few people are using the service and Google thinks that people are much more familiar with sharing content through E-Mail or other sharing services.
Google Shared Stuff was only used to share videos at Google Video and Knol articles but it is buggy and underdeveloped. Shared Stuff combined different ways to share pages with other people: by email, using social sites like del.icio.us or by adding them to a Google Shared Stuff public page
This service will no longer be available after 3/30/2009.
If you want another way to share videos, you can use the "Share" link below each YouTube video. You can also create a public Google Site if you want to share websites and links with friends.
it’s true, I prefered the email service
