This is another interesting infographic, this time around twitter’s journey to over 100 million unique users with breakdowns on key events, reasons for growth in social and mobile and a nice breakdown of twitter users in the US. One of the stand out points, is that Twitter has an awareness of 87% while Facebook is just 88% – considering the number of Facebook users, it’s a huge feat for twitter to even come close, and I suspect we can put that down to the media hype (and the celebs) surrounding twitter in the last 18 months.
