When you write a text, you know your audience and you select a language accordingly. Given that English is the lingua franca of this day and age, and given that my public is international I do write in English. However, there is nothing that stops me or any of the other people who contribute to this blog from writing in a different language.
This is a bad thing. It would be so much better when I was able to actively indicate the language that I am writing. Obviously, Blogger can have its own routines to distinguish certain languages, but I am absolutely certain that they will not recognise the majority of languages.
While I am typing this blog, I have indicated to my spell checker that I am using UK English spelling. This means that many of the mistakes I make will not be seen by you. Having indicated that the languages IS UK English, it would have been great when it was picked up by the Blogger software.
Consider, when I inform Blogger that I am writing UK English, my Firefox spelling extension does not need to guess anymore. It would provide me with a much better functionality and it would make functionality possible in languages that are not well supported..
So please blogger.com, please allow me to tag the language of my texts.
