Only 5% of users have access to the new Topic Pages for now, but Klout -- which calculates users' social influence -- will roll it out for all users within a few days.
"This is a big step for us in turning Klout into more of a utility around search and discover instead of pure vanity of checking your score," Klout CEO Joe Fernandez tells Mashable. "Our goal is just to understand what they are influential about and who they influence."
To populate a user's Topic Pages (see screenshots below), the San Francisco-based startup analyzes the user's content created across the 10 services it measures -- Twitter, Facebook, LinkedIn, Foursquare, YouTube, Blogger, Flickr, Instagram, Last.fm and Tumblr.
"We then look by topic at how influential that person's audience is about the topic and how they respond to rank the most influential people by topic. These rankings change daily based on the content created," Fernandez says.

Klout will now also use +K data to rank the top +K recipients; Fernandez compares this component to a people's choice award. The feature's "Best Content" tab will show you popular content from the past 90 days.
Klout has been collecting data about users' topics since its 2008 launch. Klout plans to add more analytics, trends and related content in the coming months.
"This is a really early version of where we plan to take this," Fernandez says, "but it speaks to our belief that every person who creates content has influence."
