Shift their habits into usefulness
#fashionistas crave visibility - give them the role of spreading compost metaphors, making the work look fresh.
#geekproblem crave edge cases and puzzles - hand them the “hard” parts (trust plumbing, metadata sieves) where their obsessiveness is an asset.
#mainstreaming crave recognition - frame #OMN as “the next big thing everyone will need to join,” so they can be early adopters without risking reputation.
Turn their weaknesses into leverage, rather than fighting them.
