Recently there has been much talk about Klout. You could call it a swelling hype. Usually a new service goes all out to get noticed but Klout has been around for quite a while. Over time the service which attempts to identify and classify influencers on social media has gained considerable influence itself.
There are already lots of lists with Klout score optimisation techniques.
Some remind me of old school SEO. Indeed, some people propagate short cuts to boost your Klout influence artificially.
While many people rightfully contest the true importance of the Klout score, it’s still one of the best ways to measure influence on the Web without resorting to simplistic metrics such as followers counts. Klout also combines several profiles into one metric. You can connect your Twitter, Facebook and LinkedIn accounts among others, so that you get an overview of your overall authority or activity.
