How important is shared history to us jellies?

At this point, fluther is over five years old, I think. There are a number of people who have been interacting for more than four years and even more for more than a year. In this time, we’ve had arguments over and over, and shared specific seminal events, like frizzer and the split of the question sections, etc.

From time to time I see questions asking about relationships with other jellies. They are hard to have when you can’t mention another person’s name (a policy that I think is a good one). Still, we are building a shared history, even if we can’t talk about it.

Since we can’t talk about it, I don’t know if there’s much point in asking, but my sense is that our history is coming to matter more. We know things about each other, even if it isn’t really written down anywhere. We have private communications. Past flirtations in public and, presumably, in private. Relationships that have begun and ended or begun and go on.

How do you think this shared history informs our current conversation? How does it change that conversation? Please use examples to the extent that you can.
