Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

From time to time I run across a profile of someone I know I've interacted with before. I rarely remember where and in what context however.

I'm thinking of something similar to Facebooks "You and David... See Friendship"-view of me and this other person.

Such page could for instance list

  • Discussions we've had (in chat and comments)
  • Which questions we've both answered
  • Which of his questions I answered
  • Which of my questions he answered
  • Which of his questions, answers and comments I've voted on


Perhaps such feature would be heavy on the database. On the other hand it doesn't really matter if such view is updated on say, a weekly basis, since more recent interactions are usually fresh in memory anyway...

What benefit would it give to the core business of asking and answering questions? – ChrisF Aug 23 '11 at 12:30
It would make it even more fun, just as badges I suppose :-) – aioobe Aug 23 '11 at 12:30

Badges are not used just for fun; they are used to promote a specific behavior. – kiamlaluno Aug 23 '11 at 12:53

I honestly doubt the usefulness of this, but here's a data explorer query that somewhat does this. It gives you all question where both of the given users either have an answer (or are the question owner), or are involved in a comment thread (either as commenter, or as post owner).

Note that this query is pretty slow, in particular on SO, it takes quite a while.

Wow, nice. The whole thing is probably actually better suited as a data explorer query :-) And I agree.. it's not really useful in that sense :-) – aioobe Aug 23 '11 at 13:16

I disagree that this would really improve the functionality and match the purpose of stack exchange sites, but I agree that it would be very cool and interesting. My request would simply be to have a little menu that shows questions you've answered for each other.
