According to the Pew Internet & American Life Project, Twitter usage has risen to 13% of US internet users in May 2011, up 62.5% (from 8% in fall 2010) as reported by eMarketer. It’s clear that Twitter usage is still growing, but for a service with a high level of awareness among the population, it still has surprisingly few users.
According to data from Arbitron and Edison Research (of U.S. consumers in general):
After laying out the numbers, eMarketer concludes that “Twitter has thus far failed to make its value proposition appealing to most Americans who have heard of it.”
Will 2011 be the year that Twitter usage really takes off in the US, or will it continue this steady (but slow) growth pattern?
