This article makes me think we need to rethink the concept of 'influencer'. If it's just a person with a lot of Twitter followers, than the leaders of our society are Katy Perry and Justin Bieber. Well, and Barack Obama too, which is cool, but he's outvoted by Rihanna, Taylor Swift, and Lady Gaga. Aaron Davis has the most insightful comment: "What stood out was the intent of self-promotion that many started with." It's the same old story - if you spend a lot of time trying to become famous, then you become famous, but you won't have spent any time doing anything worth being famous for.
