Great infographic on the world of Twitter from marketing and design agency Touch. It has a bundle of key Twitter statistics pulled together from the estimated 200 million Twitter accounts (though there are probably more) to the one billion tweets posted each week.
Interestingly it puts Twitter awareness at around 88%. Incredibly high, making it almost an uber brand. It also says that if you want that retweet the best time of day to post is 1700, but I’m tweeting this one early. Enjoy.
