Posted back in February, Kevin Weil blogged about his position at Twitter.com and his recent finding.
Kevin Weil is apart of the analysis team, analysing and measuring growth of the use of Twitter.
The graph he posted shows that shockingly over the past two years, the use of Twitter has grown exponentially. Since January 2007 to January 2010, the amount of tweets per day has grown to approximately 50 Million.
Between July 2009 and January 2010, tweets increased from 10 Million to 30 Million tweets per day.
