Google Wave
Google Wave is a new tool for communication and collaboration on the web, coming later this year. its a new personal communication and collaboration tool which is announced at the Google I/O conference on May 27, 2009. It is a web based service just like Gmail, Orkut etc, whose main purpose is to merge e-mail, instant messaging, wiki, and social networking.
It has a strong collaborative and real-time focus supported by extensions that can provide, for example, robust spelling/grammar checking, automated translation between 40 languages, and numerous other extensions. It was announced in Google’s official blog on July 20, 2009, that the preview of Google Wave will be extended to about 100,000 users on September 30, 2009. At that point, the current view of the Google Wave website (which is a preview with the keynote embedded), will be replaced with the application itself.
I think Now Google is more focused on educating the online community that’s why they are developing so many web applications related to community.
So have a quick look at wave here at Google Wave.
