Yes, Microsoft has finally launched its website named "SOCL" a few days ago. It was launched last year, but was under test until last Wednesday. It is just like a social networking site, we can post or share photos, videos or links and many other things. We can also comment on others posts. The profile page of a user on this website is just a collection of all the published posts by the user. So far it looks like an awesome effort by Microsoft and you should take a look at it.
I hope this was useful for you.
