We're not using flair for anything else, and I think it would be a lot more convenient than the wingman finder, which requires first visiting another page and then dealing with a bunch of dead accounts. Doesn't have to be a replacement, I think the two things can complement each other.

Location flair would also help when people are asking for advice, since there are some differences based on location, such as big city vs. small town vs. college town, as well as some cultural dynamics.

Lastly, the flair will make it a bit easier to remember who different commenters are, which will help build a stronger sense of community for the sub.
