Create a unified profile system to use on Microsoft Answers, Tech community and Technet

There are Microsoft Technet forums, Answers and Tech Community

1. https://social.technet.microsoft.com/forums/en-us/home
2. https://answers.microsoft.com/en-us
3. https://techcommunity.microsoft.com/

of course the TechNet's educating contents are moving to Microsoft Docs but the forums still exist.

Why not bring all these 3 sites under 1 unified roof?

I have 2 ideas:

1. merge these 3 websites into one place to find answers. if I have a question, I don't know where to post, TechNet, Answers or Tech community. maybe all 3 places? then keep track of 3 websites to see which one gets an answer first? that's not convenient at all.

2. merge the user profiles of these 3 websites so a user will create only one profile and then he/she will be able to use it on all 3 websites.
