With opinions galore that Google did not explain the purpose of its last-year-launched ‘Wave’ effectively enough; the company said at this year’s Google I/O conference that it intends revolutionizing real-time communication.

At Google I/O 2010, which began in San Francisco on Wednesday, Google finally released Wave to the Web in general – the product was restricted to the developers for the last six months, and subsequently to a limited number of beta testers.

Noting that Google was aware that it needs to do a better job at explaining Wave, Lars Rasmussen, the head of Google Wave, elaborated during a press conference that Wave has also been made a part of Google Apps. In addition, some of the other improvements that have been made include open-sourcing the beginnings of a client-server protocol.

Rasmussen added: “When we put it (Wave) out there, we did so in sort of a raw form ... what are the set of use cases, how can we make them more useful and more productive, can do it all in Wave….. But we failed to answer the question of what can I actually use Wave for, right now, right here.”

In addition, Rasmussen said that since consumers apparently do not like the idea of adding an extra tab to their browser, it is quite likely that Google Wave may end up integrating with Gmail “within a very short time.”
