Yahoo is scooping up Tumblr for $1.1 billion, gaining 108 million microblogs in the process. Just like Instagram, Twitter, and Facebook, Tumblr is another way for celebrities to connect with fans. And since they have more creative control over the sites, the content is often a more authentic and sometimes edgier expression of the celebrity's image. Pop icons like Beyoncé and Britney Spears use the site, as do TV stars Zooey Deschanel and Aziz Ansari and fashion insiders Terry Richardson and Rachel Zoe.
