Twitter power users are rare birds, according to a new report.
Twopcharts, a site that monitors web activity, found that 44% of Twitter's 974 million registered users have never tweeted, according to The Wall Street Journal. Some 30% of existing Twitter accounts have sent 10 or fewer tweets, and just 13% of registered accounts have tweeted more than 100 times. Twopcharts is unable to discern whether users have logged onto their accounts. Its report is based on users' activity.
