We can engage with people outside the rule-bound linear progression of offline relationships, and discover information about another person, miles and years from the person they were when they were posted it. Try responding to a post on a message board dated a while ago, maybe 10 years or more. That person might have lived in five cities between then and now, and fallen in and out of love three times, but the person they once were remains a notational snapshot trace, as if it were yesterday, offering thoughts on gardens, allergies, movies, or recipe ingredients.
