Bebo has announced a new partnership with Microsoft that will see the introduction of the Windows Live instant messaging service to Bebo’s social network.

The new service will allow Bebo users to chat to people outside of the Bebo network, from within Bebo itself. What makes the deal perhaps more interesting is that Bebo users will also now be recognized over the Windows Live platform; in effect the deal becomes a sort of merging of member databases. It’s also a first for Microsoft, who has remained somewhat distant from the growing social networking market to date.

Bebo continues to trail behind MySpace and Facebook in the United States in terms of traffic, but as confirmed by comScore August 15, is the most popular social networking site in the United Kingdom.
