Flair (Reddit)
Small labels/badges on Reddit set either on posts (category, e.g. "Question", "News", "Spoiler") or next to a user's name in a subreddit (role, team, expert status). A customizable way to organize and express identity.
Two types: post flair categorizes posts so they can be filtered (a sports subreddit has "Trade", "Highlight", "Discussion"; a support subreddit "Solved"/"Unsolved"). User flair is set next to the name and shows affiliation or status — a favorite team, "Verified developer", a joke epithet. Moderators control which flairs exist and can assign some (e.g. expert badges). Win: it makes large subreddits navigable (filter by flair) and builds community identity and culture. A small but culturally rich feature that varies enormously between communities. Related to karma and automod.
