Pattern: First, one of us gets a bright idea on user-friendly interface (here: fractional sizes like 1.5M). Objections, if any, get brushed aside.
Then the thing sprouts warts, tentacles, sores, and starts to give off that sickly-sweet smell of bugs feasting on misguided ideas. Until one of us spends a lot more time on containing and reducing the damage than the thing could ever be worth. Cobbler, stick to your last. Thanks, Eric!
