Pingdom has published an analysis of the number of tweets that Twitter is processing, and the results show that Twitter continues to grow. As of December, Twitter is processing more than one billion tweets per month. January passed 1.2 billion, averaging almost 40 million tweets per day. This is significantly more than Twitter was processing just a few months ago, double what it was in August 2009.
This is the first time that I’ve seen data showing activity from all sources, including third-party applications via Twitter’s API.
