I am happy for one reason only:
I called it. Two months ago:
Nick Nicholas’ answer to What’s the next useful and perfectly good feature that Quora is going to do away with?
*touch wood* Blogs.
The current trend though, is away from social media functionality, and has been deemphasising your followers. So:
Less Wild speculation:
In the display of your followers, or the mouseover display of a user: the followers you have in common.
It’s the last piece of the puzzle: MVW badges and TW quills have already been taken away from the former.
EDIT: Yes, Quora has put the mutual followers field back.
