Twitter already stated earlier in the week that it was geting about 50 million tweets being sent out per day. New data released shows that approximately half of those tweets are in non-English language. Approximately 25 milion foreign languge tweets being sent out per day.
A lot of people are using Twitter in languages other than English, and those numbers are expected to grow, as Twitter recently has put out statements seeking help to crowdsource their platform into FIGS.

The number one language aside from English is Japanese, with approximately 14% of all tweets being sent out in Nihongo. Portuguese, Malay and Spanish closely behind.

Dave Lakhani has an interesting post on the future of marketing and mass communication in which he coorelates it with singularity.

So as I studied The Singularity it occurred to me that the answer to how do you get your message to the masses and have it be heard most likely won’t be answered by us, it is much more likely to be answered by the individuals collectively that we hope to communicate to. In fact, it is my belief that another form of singularity will occur, in which potential customers will become evermore sophisticated in their ability to filter and consolidate information. As they become more sophisticated, they create individual influence streams from which they get all of their information, information that is highly personalized and highly selected. Rather than trying to increase the number of people they follow they become increasingly selective about who they receive information from ultimately reducing the noise while becoming much more connected to the channel through which they receive information. RSS was the first glimpse and promise of the idea that you could consolidate the information that you wanted into one single feed. In social media FriendFeed is trying to do that. And overall web wide Twine is also trying to do it. But for most consumers they don’t go far enough.
