It was announced yesterday that Google Wave (above), a new service enabling users to exchange messages, images, songs and videos in real time, will be released to 100,000 hand-picked Google enthusiasts in September. Technology correspondents are gearing up for months of speculation at the impact of yet another bold announcement from the Californian company. In this era of Twitter and Facebook, with hundreds of millions of internet users hooked on letting the world know what they’re up to, it’s Google’s belief that there’s room in the market for yet another service. I wish I understood how to use any of them !
