On Monday, Twitter shared an interesting metric that shows its staggering growth in usage.
Kevin Weil, a member of Twitter’s "analytics team," wrote:
The graph above tells a story of how we’ve grown over the past three years in terms of number of tweets created per day. Please note that tweets from accounts identified as spam have been removed so the counts in this chart do not include spam.
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.
Weil said the company plans to release more metrics like this soon, which will only fuel speculation that Twitter is planning to introduce advertising within its stream — something Twitter has so far resisted.
