I have been giving a keynote talk at a London conference organised by the Market Research Society on the case for sharing ownership of information and research about us as consumers.
Some of the figures that emerged during the day, from the agency WhiteVector, point to the extent to which shared content online is growing.
1 billion tweets are sent each week. 1 billion pieces of content are loaded on Facebook each day. And for each minute that passes, forty eight hours of video are uploaded to YouTube.
Like it or not, we are linked up, down, in and out.
