Google [GOOG] launched Google Wave about a year ago in June 2009. A long beta test was done with the service which then finally opened up for general use. Since it fully opened the take up has not been the best and the service really hasn’t taken off like Google would have hoped for.
Because of this, Google is now killing off the Google Wave service, but will continue to support it for the remainder of this year.
Wave has not seen the user adoption we would have liked. We don’t plan to continue developing Wave as a standalone product, but we will maintain the site at least through the end of the year and extend the technology for use in other Google projects. The central parts of the code, as well as the protocols that have driven many of Wave’s innovations, like drag-and-drop and character-by-character live typing, are already available as open source, so customers and partners can continue the innovation we began. In addition, we will work on tools so that users can easily ‘liberate their content from Wave.
