Trying to describe Microsoft's Windows Live family of web-enabled tools for Windows has been a bit like the parable of the blind men describing the elephant.

Is Windows Live a photo sharing service? A file sharing service? An email service? An IM service? With the news that Windows Live is adding connections next week  to many other popular Web 2.0 social networks, it's easier now to say, as ArsTechnica puts it, that Microsoft wants to:

[T]urn Windows Live into the average netcitizen's main hub for his or her social life, or at the very least to turn Windows Live into a social network.

Microsoft's teaming up with lots of social-networking partners around the world. US-based companies becoming BFFs with Windows Live include MSN, Digg, Facebook, SmugMug, and MySpace (see the full list of 31 current and new partners here).
