I have to use chatter in force.com sites. I have used <chatter:feed entityId="{!$User.Id}"/> in Vf page. Through VF pages if I click preview button I can see chatter page. See below 
But When I am using this VF page in force.com site. It shows blank page.
How to use chatter in force.com site ?
Note that Chatter components don't render for Visualforce pages using Force.com sites.
