Who uses Twitter?

A new Pew Internet publication looks at how Americans use social network sites like Twitter to keep friends, family and/or total strangers updated about their lives. As of Dec 2008, 11% of online American adults have used a microblogging service like Twitter. Not surprisingly, age has a lot to do with who “tweets.” From the publication’s summary:

“Twitter and similar services have been most avidly embraced by young adults.3 Nearly one-in-five (19%) online adults ages 18 to 24 have ever used Twitter and its ilk, as have 20% of online adults ages 25 to 34. Use of these services drops off steadily after age 35 with 10% of 35-to-44 year-olds and 5% of those ages 45 to 54 using Twitter. The decline is even more stark among older internet users; 4% of 55-to-64 year olds and 2% of those age 65 and older use Twitter.
