Ben Goldacre, whose Bad Science blog and column in the Guardian keeps journalists writing about health in check; Hilary Alexander, fashion director of the Telegraph; Jemima Kiss, technology writer at the Guardian; Robert Peston, business editor for the BBC and Mike Butcher, editor of TechCrunch UK have all been ranked by PeerIndex as the five UK journalists with the greatest online influence.

PeerIndex measures social capital using a method very similar to that which Google uses to calculate its page rank. It automatically ranks those with a Twitter account but users can also add LinkedIn, Facebook, Tumblr and Quora accounts.

Here is a snapshot of stats on how the top five people in the list of the UK’s 100 most influential journalists online use social media.

Jemima Kiss was the most-followed British journalist on Twitter for a couple of years, but maternity leave allowed others to overtake her, even though she announced her son’s birth online within hours of the fact. When she is active her feed is a very social mix of articles, conversation, pictures and observations.

Robert Peston is another “name”. His Twitter account consists extensively of links to articles and observations. However, he does retweet and reference people in his observations even though he is not a conversational tweeter.

5. Mike Butcher @mikebutcher
