Thanks for all the positive feedback 
I'm leaning towards a 2 or 3-part article on our intranet pages - 1. introduction to winter biking, covering just the basics and how to ride comfortably down to 0 deg C, with maybe an option to buy the basics through me, - 2. intro to riding below freezing: studded tires, good specialized winter biking clothing (tights, jackets, winter shoes) and maybe - 3. useful tips for riding down to -15 C, which is about as cold as it gets here, thermo shoe covers, lobster gloves, how to protect your face, winter maintenance tips.
It's taken me several winters of regular commuting to figure out what works best for me, so I'm thinking this could be useful to pass on to others. I have to be a bit careful about getting preachy, though
I can't stand wearing waterproof stuff unless I really have to, for instance, but I pass people every day wearing expensive Goretex shells in dry, sunny weather
so I have to assume opinions differ.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
