Klout recently announced the inclusion of more online services as input to its scoring system namely YouTube, Tumblr, Flickr, Blogger, Last.FM, and Instagram
. I guess this is good news so that one's influence score will not be based on vanity metrics such as following but look further into two-way interaction.
However, I am not in favor for Instagram
to be included as a Klout
scoring input signal. Simply because, you need an iPhone to be able to use Instagram and not all has one. An influence scoring system should get data from applications that anyone can have access to.
Anyway, that is just my take. :)
