Came across this neat widget called Mini Site Translator from Widgetbox.
Visitors can click on the flag of their country to have the content translated into their language of choice. Be it French, Spanish, Portugese, German, Italian, Russian and Chinese, apart from English, of course.
This could be an useful add-on to your blog as it helps those who may prefer to view content in a language of their choice.
I must add that putting the widget was not too difficult either.
