Today the word “Google Wave” is Trending globally in Twitter. And, the word “Google Wage” is also trending in few countries e.g India.
Actually Google already announced about closing “Google Wave”, and right now it is NOT having any plans to start any new service with the name “Google Wage”.
The only reason for this trending is, a small typo error made by Google Team when sending the Service cancellation email to Google Wave users. The service cancellation email carries the “From” field as “Google Wage” instead of “Google Wave”.
