Not any time soon. Right now, Steam only offers an Open ID mechanism, which is very different than the much more robust Oauth services that all other social networks provide. Open ID only provides for authentication, without any profile or other data imports.
While that is useful to some extent, it's not something we have any plans to implement in its current form. It's also not something that's ever been requested before, which is a good indicator for demand, which is one of the ways we prioritize things.
I hope that helps explain, even if it's not what you were looking to hear.
Thanks,
Alex
