This is even more true when looking at the components underlying the "new" website translator gadget, some of which have been around since as far back as 2007.
On the other hand, it also happens to be International Translation Day which could be the root rally point for both products launching today. Regardless, it seems like Google is capitalizing on a good time to repackage and remind everyone about their own free translation tool for webmasters.
Installing the gadget is as simple as cutting and pasting a few lines of code into your webpage. After that, if a visitor whose language specified in their browser settings is different from yours, a translation banner will automagically prompt them to translate the page.
Similarly to Facebook's approach, Google incorporated a human element into their Translator Toolkit, which helps their primarily automated translation system "learn" from its mistakes. The Google Translate ecosystem is now up to supporting 51 languages, which is still shy of Facebook's 65.
