While archiving some old files just now I came across this article, which I wrote for Viewfinder magazine last year. Viewfinder is the magazine of the British Universities Film & Video Council, and the article is pitched at helping academics think about how they could (should?) use a tool like Twitter in their academic life. It leans a little towards being for my subject area, but I think generalises out pretty well. Also, it seems to still make sense even after a year, which is good going for an article about social media.
