The frequency of new content is one reason Kia Haslett (@khaslett) visits jezebel.com more than once a day. Is her reply representative of the general population? If it is, it might provide one reason why people visited Facebook more than Google this month.

Every time you visit Facebook or open up your favorite Twitter application, you see new content from a very personalized list of sources: your friends.

Google doesn't greet you with new content. It says hello with a search box.

What about Web sites and blogs? Even frequently-updated sites simply can't compete with the frequency of status updates on social networks.

So how do journalists and news organizations fit into this picture? They need to work hard to be invited into the personalized streams of people interested in the content they produce, find and share.
