Yep there's lots of us... people from all over the world, really! Though I'd say the vast majority are from the USA....
The only thing where the metric/imperial system fails is in our 'signature line trackers' - if you track your weight in kg, the sig-line tracker converts it to pounds, and shows you weighing near double what you really do... the way to fix that is to go to your start page, click the link for account/email preferences, and look for the little check box "use metric system" - uncheck it, and your sig-line tracker works.
I find the nutrition database is very metric-friendly - sure a lot of items are in there by the pound, but most of the basic groceries are in there with "grams" in addition to "ounces" and "cups"...
