Google is one of the most influential users on Twitter, according to a study by Hewlett-Packard.
The research by HP Labs analysed 22 million tweets and separated "influence" from "popularity" by assessing engagement with followers rather than the number of contacts they have. The study found users @Google, @Mashable, @jokoanwar and @michellemalkin were some of the most influential users on Twitter.
"This study shows that the correlation between popularity and influence is weaker than it might be expected. This is a reflection of the fact that for information to propagate in a network, individuals need to forward it to the other members, thus having to actively engage rather passively read it and cease to act on it," said the report.
Using the "Influence-Passivity Algorithm", HP's social computing lab scored users on the quality of their audience and how difficult it was for other users to influence them.
PeerIndex recently launched as the first platform for recognising authority on the web, attempting to rank web users according to their authority on different subjects rather than the number of contacts they have.
