Semiocast has published a report which claims that English today forms less than 50% of all tweets posted on the Twitter network.
This means that majority of tweets are now in other languages. English remains the dominating force with around 39% market share.
Japanese comes at the second spot with around 14% tweets.
The report also said that around 0.5% tweets are currently in mandarin despite the fact that Twitter is blocked in China.
Twitter is perhaps the best example of how a web based service can be adopted globally with each user establishing their own purpose out of it!
