Updated for 2009: What the F**k is Social Media?

Last week we posted a link to Martha Kagan’s original “What the F**k is Social Media?” presentation. A year later, Kagan has updated the presentation.

Here’s why social media should matter to you (and your brand):

• 3 out of 4 Americans use social media
• 2/3 of the GLOBAL population visit social media sites
• Visiting social sites is the 4th most popular online activity — higher ranked than personal email
• Time spent on social sites is growing three times faster than any other activity online
