Honestly, it'd be pretty neat if Microsoft setup their own instance and consolidated all of their communities onto it. The user part is optional. Since it was federated, you could post to it from other instances (right...? Provided they don't get black listed).
I feel like Microsoft has 10 different community forums for all different aspects of their business. Centralizing it onto an instance like this with magazines for each would actually be reallllllly helpful.
It's sort of surprised they were able to get the Rblind.com domain.
No way they would've been able to get blind.com. So domain wise it makes sense.
