Twittersphere is growing. In 2008 Forrester Research estimated that, Twitter had 4-5 million users and Nielsen Online showed on its report, Twitter ranked No.1
In a new report, Nielsen reveals that Facebook users spent an extraordinary 13.9 billion minutes on the site - in the month of April alone. Lagging far behind, at 5 billion user minutes, is MySpace, the network launched in 2003, and purchased by News Corp. in 2005. For years, MySpace was the go-to networking site, but it recently lost significant ground to Facebook and Twitter.
But fundamentally, this micro-announcement service does serve two needs: to post updates with low overhead and to follow a concise stream of updates.
If you care about productivity, don't check your Twitter feed while you're trying to get work done. Disruptions are deadly for productivity because it takes several minutes to reorient the brain every time you go off track looking at something else. Stick to checking updates once per day—for example, during lunch. All the tweets will still be there.
