Klout; any clout?

There has been much discussion recently about Klout, a website which claims to analyse online influence. On 17th October 2011, I had a score of 34 (whatever that means), and was described as being influential about the ‘Federal Reserve’ – see here.

Almost two months later, I am advised that my score has increased to 44, together with an increasing number of people it claims that I influence. However, I now appear to be influential about Law, Fraud and Voting in addition to the Federal Reserve.

I would therefore like to ask the people behind Klout:
On what basis am I influential about these topics, of which I have relatively little interest?
