The free tool, offered by Google on Thursday during the Mountain View, Calif.-based company's annual conference for software developers, runs in a web browser. It contains elements of e-mail, instant messaging, wikis and photo sharing. All this was done in effort to make online communication more dynamic. As Google hopes that tool simplifies the collaboration and opinion sharing among people. Google Wave will be available to the rest internet users later in this year.

As it is known, Google wants this service to evolve even more with the help of independent computer programmers, who can find new ways to use the service.

Among other things, Google is counting on outsiders to figure out how to weave Wave into the popular Internet communications service Twitter, social networks like Facebook and existing Web-based e-mail services, said Lars Rasmussen, a Google engineering manager. He faced such a phenomenon during build of Google's online mapping service, which sprouted a variety of unforeseen uses after its 2005 debut because of the ingenuity of external programmers.

Wave allows communicating easier over e-mail. It provides tools to highlight particular parts of the written conversation. There is a possibility of transplantation into the service of photos and other online applications known as "widgets". The service could easily accommodate advertising like Google's 5-year-old e-mail service already does. But as Lars Rasmussen thinks it is very early to predict how the company may profit from Wave.
