At the risk of being thoroughly tiresome and because I'm interested but lazy, can I just paste the comments below as a contribution? They are from a short article I wrote a couple of years ago in a newspaper supplement here. Hope they are of some interest.

Languages on the Net
With regard to the use of different languages on the world wide web, it is interesting to note that in 2004 there were 7 million people in Thailand accessing the internet and other online facilities. Of this 7 million, 4.9 million were doing so in Thai. This means that 2.1 million internet users in Thailand were using a language other than Thai for connection with the world wide web. In other words, 30% of internet usage in Thailand is by means of a non-Thai language. One would assume (but without the data) that most of this 30% is in English. Clearly, for a high proportion of Thailand-located web users, English is the most convenient language. You might like to look at

English in Decline?
The internet data would suggest that English is unassailable as the language of international communication, something with which this writer would agree. However, my attention was drawn recently to an article on the National Geographic website:
http://news.nationalgeographic.com/news/2004/02/0226_040226_language.html advising that the status of English may be about to peak and then decline.
Reading beyond the headlines, however, it is clear that this decline is only relative, in terms of the total native-speaker population (340 million) and its proportion of the world’s population. Whereas 9% of the world spoke English as their mother tongue 50 years ago, the figure is now only about 5%. Mandarin Chinese is well established as the world’s largest language in terms of native speakers. However, the number of speakers of Mandarin as a second language (200 million) is only 40% that of English as a second language (515 million) and 90% of Mandarin second language speakers are in China. It’s also worth noting that, in China, about 250 million people are learning English. By comparison, there are only 20 million students of Mandarin as a second language throughout the entire world, of which 75% are in Asia. The world is becoming increasingly bilingual, and easily the most popular and influential second language is and will most likely continue to be English.
Speaking of influence, another study reported on the same website, has found that the position of English as the language of Science is strengthening. At present, 90% of journal literature in some scientific fields is in English and there is no sign of the influence of English diminishing in the scientific world.
Indeed, though its native-speaker population may be in relative decline, this fact needs to be balanced by the growth in numbers of second language speakers of English whose ability is at or close to native speaker levels. More and more second language speakers throughout the world now have high levels of competence in English. These people will pass on their enthusiasm for the language to their children and this phenomenon is not going to decline.
