UPDATE: Google Disco Discontinued.
Yesterday I posted about Facebook Acquiring Beluga to make use of their mobile group messaging technology.
Mobile Group Messaging War
Enter Google Disco
Their new service, Disco, is offered both as an online service and as an iPhone application. No Android download yet, due to the acquisition of Slide; yet this very same Slide acquisition gives Disco the ability to support Facebook integration in order to import your friends, etc.
Disco is extremely bare-bones currently and I’m guessing Google just wanted to get into the competitive landscape ASAP.
