Tweety Twitter Tests

eMarketer estimates there were roughly 6 million Twitter users in the US in 2008, or 3.8% of Internet users.

eMarketer projects that the number of Twitter users will jump to 18.1 million in 2010, representing 10.8% of Internet users.

comScore reported that Twitter.com drew 4 million unique visitors from home, work and college/university locations in February 2009, up from 340,000 a year earlier—a 1,086% increase.

Nielsen Online reported 7 million unique visitors to Twitter.com during the month, up even higher—1,381%—from 475,000 the prior year.

comScore also reported a surge in March. After months of double-digit growth, traffic to Twitter.com accelerated 131% to 9.3 million visitors for the month.

And the number of Twitter users is considerably greater than the number of visitors to Twitter.com, as a result of the multiple access points for the service (for example, mobile devices and desktop apps).

A survey of Twitter users from MarketingProfs backs Mr. Williams’ views. On a scale from 1 to 5 (with 1 for strongly disagree and 5 and for strongly agree), the phrase “I find it exciting to learn new things from people” averaged a score of 4.65 and “I value getting information in a timely manner” averaged 4.58.
