It might be a little creepy for some but the fact that you can see your business contact's Facebook picture when composing an email on Outlook is all a reality now. I actually use Xobni for MS Outlook and my contact got freaked out when I told her she has a nice picture. Now Xobni released a version on Gmail.
Do you know or use any other social media integrator for your email?

I now find myself in a situation where I get more Facebook friend requests because of the integration of thse social media plug ins in email.
