Just to play devil’s advocate here, I think that there are specific and relatively universal standards of “cool” that people look for in others’ identities. I think it’s more difficult to give these off in person than it is to portray these online. So for people who are worried about how they might come off in social situations and the over-thinkers, this is a huge blessing because they can carefully manage others’ impressions of them if they know what they’re doing. Which, like it or not, is an incredibly valuable skill to have these days.
