And no, we’re not talking about this in terms of herpes or the clap, but rather the above chart demonstrating that Twitter has become bonafide over the last year. Even if, say, half of all tweets are sent by SEO marketers.
From the Twitter blog:
Folks were tweeting 5,000 times a day in 2007. By 2008, that number was 300,000, and by 2009 it had grown to 2.5 million per day. Tweets grew 1,400% last year to 35 million per day. Today, we are seeing 50 million tweets per day—that’s an average of 600 tweets per second.
