Wow, don't know if this feature has been there a while or not, but when you auto-translate a foreign-language page from Google search results, it automatically adds a hover/tooltip functionality for each line of text, allowing you to "see" what the original text was (thus making it easier for those of us who occasionally read non-English news or developer websites, to make a "guess" at what a poorly-translated sentence might mean)
Example (http://translate.google.com/translate?hl=en&sl=zh-CN&u=http://jsvm.org/forums/1904/ShowPost.aspx&sa=X&oi=translate&resnum=4&ct=result&prev=/search%3Fq%3DJSVM%26num%3D50%26hl%3Den%26lr%3D%26safe%3Doff%26sa%3DG%26domains%3Den.wikipedia.org%26pwst%3D1) (hover over some text and see what I mean 8) )
"This page was automatically translated from Chinese (Simplified). View original web page or mouse over text to view original language." <-- how long have I ignored that verbiage? ;)
The internet isnt only English?! WTF?
That's sorta neat. Now to find content in a language other than English, that I actually understand!
