Google Maps linked with Twitter to bring you Super Tuesday 'live' with dynamic news updates and personal tweets from across the country.

Effectively, this created a one night national network of local citizen commentators, limited in numbers only by the inclination and resilience of individual Twitterers to participate (they were still going strong when I posted this).

I got pointed at this by Pete, who heads up our content team in London. Pete will shortly join the roster of contributors to TNM, so I'll have to get used to finding my own stories.
