"Today we’re excited to announce the launch of a new version of Klout that helps you not only measure your influence, but also increase it."
Looks like @klout is offering a new feature that is essentially @buffer. Makes sense to me. Not that one's Klout score is definitive, but I often check it to get a sense of "social influence" and their Chrome extension on Twitter gives you a sense of one's activity/influence. It follows that they would offer a means to help you improve your Klout score.
How long until @buffer starts offering scores for its users? :P I agree, I don't think @buffer has anything to worry about here having garnered quite an audience.
