CYBERSPACE (AP) -- The White House has joined the popular social network sites of Facebook, MySpace and Twitter.
The Executive Mansion's Web site now has links to the features on its main page.
The sites contain information about swine flu and will be updated with information on other topics as time goes by.
A White House official says the Obama administration won't be able to reply individually to people who send messages through the sites.
But he says people who join can speak to each other and those thoughts can, in turn, be shared with the White House.
