How many tweets did you send yesterday? None? Dozens? Together, we manage to send around 200 million tweets every day, Twitter has said, compared with two million a day in January 2009 and 65 million a day this time last year.
I can’t supply you with a figure for the percentage of those tweets yesterday that were about whether Johann Hari is the worst person ever/unfairly maligned victim of a Twitter witch hunt. Twitter has, however, made a list of the things that have most been concerning its members over 2011.
