Roundup of the Twitterverse in 2009 according to the BBC

2009 seen through Twitter activity helps us to realise how communication is changing.  The role of the web has been extended as twitter became more mainstream.

The 3 most striking features seem to be

twitter bystanders are ahead of the traditional “newsgatherers” even at formal political events (G20, Iran)

twitter is a place where people want to express personal emotions (death of Michael Jackson)

twitter has become much more of a political force (think of Joe McElderry caught in the crossfire.)
