According to an announcement by Klout product manager David Temple, “If you’re one of Red Bull’s top advocates, they’ll keep you informed with a subscription to The Red Bulletin and make sure that you’ve had a chance to try their new Red Bull Total Zero by sending you a 4-Pack. The very top influencers will get some sweet merchandise or even a VIP Red Bull experience, like a behind-the-scenes look at the X-Games.”

Scoring models are in the works for several more services: YouTube, Instagram, Tumblr, Blogger, WordPress.com, Last.fm, Flickr, Quora, Yelp, Posterous, Livefyre, Disqus, bit.ly, and BranchOut.
It's unclear exactly how top influencers are calculated, as well as how smaller brands might be involved in the future. At this point, it's too soon to tell how brands can benefit in a significant way, but Klout will most likely continue tweaking in the coming weeks.
