Pew Internet released the results of a new survey recently. “Twitter Use 2012″ explores the current use of Twitter through data collected from telephone interviews from January 20 to February 19, 2012, among a sample of 2,253 adults, age 18 and older, and from March 15 to April 3, 2012, among a sample of 2,254 adults, age 18 and older. According to the survey, 15% of online adults use Twitter, and 8% do so on a typical day. The use of Twitter rose from 13% in May 2011 to 15% in February 2012, although the proportion of online adults who use Twitter on a typical day doubled in the same time frame. Increased smartphone use is thought to account for much of this growth, as smartphone users are particularly likely to use Twitter.
