The key is to understand how other people respond to a tweeter. Your rating is a function of other people’s assessments. This process, a bit like voting, is harder for a single individual to ‘game’. Each person is then assigned a UK π-score (Pi-score) from 1 to 100. This being the top of the tree, all of our Top 140 have scores above 92. The Uk π-score is an influence score in the context of the UK Twitter sphere.
For the Twitter 140, we focussed only on whether other people in the UK were responding to, retweeting or engaging with a tweeter.
Our maths also assesses who the people engaging with an influencer are. So a retweet from someone highly influential is worth more than a retweet from an average person. The number of followers does not factor in the weighting.
We crunched around 10bn tweets and looked at more than 150m accounts on Twitter to generate this list.
We did a couple of small pieces of editorialisation:
We excluded all corporate and brand accounts, such as newspapers.
We excluded parody accounts.
We excluded journalists from the main national newspapers. We may do a separate journalist table in the future.
We included a couple of Brits who are transatlantic, like Piers Morgan; as well as Caspar Lee, whose audience is heavily British. We kept will.i.am in because he always seems to pop-up on British TV. We made some other small judgements about where people were located to ensure the list was reasonably accurate.
