It may be a little later than the 2Q2006 originally promised, but Microsoft and Yahoo’s effort to provide instant messaging interoperability has left the beta started in July and will go live tomorrow:
Yahoo and Microsoft announced that they would tear down the wall between their formerly exclusive instant messaging services and allow members to mingle beginning Wednesday.
The union of Yahoo Messenger and Windows Live Messenger systems would create the world’s largest combined IM network with nearly 350 million users, the US companies said in a joint release.
Users will need to install the latest versions of Yahoo and Live messaging software to make connections. The companies said the programs would be available for free download from their websites.
