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...
