Simon Sanders at Lansons alerted me to a new study, based on a concept initially developed by Forrester Research.

The aim of the study was to identify the various different types of social media user. Lansons has defined nine types of user, as shown in the chart below…

A number of these user types are based on Forrester’s work around ‘social technographics’. Some have been adapted and re-labelled, whereas others are entirely new.

The two new categories are Commercialists and Collaborators, the former being interested in social media for business reasons, while the latter are more concerned with sharing and co-creation.

There’s more explanation about each of the types on the Lansons blog.
