OK, so it might be a bit late for this, but: Shouldn't it be called "flare" instead of "flair"? I'm talking, of course, of the stuff stackoverflow gives us.
I looked at Merriam-Webster, and neither word has a meaning approaching "badge" or "shiny graphic to put on your web page".
For "flair" I see: "An instinctive ability to appreciate or make good use of something"
For "flare" I see: "a light (...) designed to attract attention". "to flare" comes even closer to the meaning we have in mind: "to display conspicuously".
If one looks at the urban dictionary, we see "flare" defined as: "Any unwanted accessory that must be worn by your place of employment. (Just see the movie Office Space) "
Based on this, I think it's clear that the correct spelling is "flare". Using the wrong spelling might confuse everyone and make the world a slightly more confused place. Certainly, we want no such thing?
I don't know how difficult it would be to change the spelling throughout the stackoverflow site, both technically and if the term really is trademarked, as the stuff stackoverflow gives us (jokingly?) indicates.
The question, then, is: dear reader, do you think we should replace "flair" with "flare"? And - why?
