5B and Flat for Twitter

TweetNo5B.jpgThe good news for Twitter: The social-networking service reached tweet No. 5 billion. The bad news for Twitter: Traffic has been flat for the past two months.

CNET reported that former Current Media executive Robin Sloan was responsible for the milestone tweet. Sloan recently left Current to work on novel Mr. Penumbra’s Twenty-Four-Hour Book Store, which he is financing through Kickstarter, according to CNET.

Meanwhile, comScore reported that traffic to Twitter.com was essentially flat for the past two months, hovering below the peak of 21 million U.S. unique visitors it reached in July, Silicon Alley Insider reported.

Silicon Alley Insider pointed out, however, that a generous amount of Twitter traffic does not go through Twitter.com, including that from third-party applications, other Web sites or text messaging.
