1) An oldie but a goodie. Forbes: "Klout CEO on Raising Your Score, Google Plus Integration, and Justin Bieber's Perfect 100"
This is one of the best breakdowns I've found re: how the platform works, what you need to know, etc. It's slightly out of date, as many of the integrations Joe speaks about have already happened, but it's still my favorite reference.
2) The Official Kout Online Blog: "The Tech Behind Klout.com"
Not for the faint of heart. But if you're ready for an R-rated look at the blood and guts of the UI, then get excited.
3) Buffer: "8 Facts And Figures About Klout You Might Not Know"
The average Klout score is only 20. This should make most of you proud to know that you're well above average ... but we already know that because you got into Stern.
4) Elle: "Ask E. Jean: Want to Raise Your Klout Score? Read This"
(For the record, your professor, and my boss, @ProfGalloway, has a stable Klout score of 60, and tweets for himself.)
Phenomenal advice from Klout's @MeganBerry (who is fast becoming one of my favorite people EVER, follow her if you don't already!)
"We've found that when people are authentic and share their true feelings about their area of expertise, they influence more people to take action and their scores go up." #word
5) The Huffington Post: "Most Influential Chefs: Klout Ranks The Top 10 By Social Media Impact"
This one's on the list because I know @KerenRM will love it, and since she managed to tweet FROM CHINA, she gets a special treat upon her return ;-)
