This was brought up as a request in the /c/autism community. The idea is that post can be flared with a tag that categorizes a post, telling users what type of post the user made. The flair would appear before the post title. In the case of /c/autism, the categories could be meme, discussion, venting, seeking support, education, question, etc. This would allow another user perusing the community to know if the post is worth looking into. www.reddit.com/r/autism has some good examples.
