Ethan Shen, who has become quite an expert on the various machine translation (MT) engines, has launched a nifty web service designed to help you improve your language skills: Gabble On.
Basically, the site leverages an MT engine (Google, Bing, Systran) to display a news article in the target language.
It’s still a work in progress, but I like the way it displays source and target sentences side by side so you can follow along sentence by sentence.
I think the site has the greatest potential for teaching vocabulary.
Ethan welcomes input so give it a test drive and tell him what you think!
