Bing, Microsoft’s alternative to Google Translate, is used by Twitter to provide instant translation for users.
However, it isn’t very good, as this blog has repeatedly pointed out.
And it doesn’t look as if any improvements will be forthcoming soon, if the evidence below from your correspondent’s Twitter feed today is to be believed, where Bing mistook English for Estonian, a language belonging to the Finnic branch of the Uralic language family.
If Bing cannot even identify the language correctly, one has to question the quality of any translation it produces.
