A while ago there was an article about famous Belgian Twitter users. The article gave an overview of the "most influencial" people based on their Klout score. Although these metrics aren't always accurate (he who shouts the most and the loudest gets the best score), I found this graph interesting:

It tells me I'm a networker, just like Bart Boucké:
You know how to connect to the right people and share what's important to your audience. You generously share your network to help your followers. You have a high level of engagement and an influential audience.
Whether this is true or not, this I the role and style I aim for on Twitter. This is why I'm using Twitter.
The other people on the graph are Dries Buytaert (Drupal). He's the one with the highest score in my graph, and he's is a Thought Leader: You are a thought leader. Your followers rely on you, not only to share the relevant news, but to give your opinion on the issues.
I don't know the identity of @felixhoenikker9; he's a VC, but that's not the reason why I'm following him. I'm following him because of his open source CleanTech blog (which is in line with our own mission statement). He's a Socializer.
Balder Van Camp is an iText developer, and a Conversionalist: You love to connect and always have the inside scoop. Good conversation is not just a skill, it's an art. You might not know it, but when you are witty, your followers hang on every word.
In the Explorer style, there's Bart Farasyn, David Damen and Patrick Debois. I know Patrick since 1997 and we've met each other on many different occasions ever since. I don't know Bart and David that well, but I've been following them for quite a while now.
Finally, there are the Specialists: Amedee Van Gasse and Pieter Colpaert, two people I met at GentM (or, in the case of Amedee at a BarCamp), who are described like this: Your opinion is second to none. Your content is likely focused around a specific topic or industry with a focused, highly-engaged audience.
As you can see: there are people with a higher Klout score and people with a lower Klout score than I have. I don't think that score really matters. What I like most about this Klout graph is that it seems to be consistent with how I perceive the different people shown on the chart.
