Will Google's Wave Replace E-Mail—and Facebook?

Google has big plans for Google Wave, its new online communication service—and they won't all come from Google.

The Web search giant is hoping that software developers far and wide will create tools that work in conjunction with Wave, making an already multifaceted service even more useful. Google (GOOG) is even likely to let programmers sell their applications through an online bazaar akin to Apple's App Store, the online marketplace for games and other applications designed for the iPhone. "We'll almost certainly build a store," Lars Rasmussen, the Google software engineering manager who directs the 60-person team in Sydney, Australia, that created Wave, told BusinessWeek.com. "So many developers have asked us to build a marketplace—and we might do a revenue-sharing arrangement."

Combining instant messaging, e-mail, and real-time collaboration, Wave is an early form of so-called real-time communication designed to make it easier for people to work together or interact socially over the Internet. Google started letting
developers tinker with Wave at midyear and then introduced the tool on a trial basis to about 100,000 invited users starting on Sept. 30. Invitations were such a hot commodity that they were being sold on eBay (EBAY). For Google the hope is that Wave, once it's more widely available, will replace competing communications services such as e-mail, instant messaging, and possibly even social networks such as Facebook.
