I was wondering about scale popularity. I decided to look at eBay auctions. I simply took the number of currently running auctions in each scale and charted it. Now of course this is skewed a bit due to being US, time of year, multi-scale items, etc. But, it still proves thought provoking. What really caught my eye is that I had no idea that O might be as popular or more so that N. Anyway, just interesting.
