There some good practical reasons to not have the numbers listed next to categories.1. It's kind of inelegant, it's not something you see on Amazon or Ebay for this reason.2. The number of listings gives open source intelligence to LEO free of charge. They should be forced to do their homework instead.3. The numbers are not a reliable guide to SR anyway, because not all listings are publicly available.4. The numbers are not a reliable guide even if they were, because listings are used in different ways by vendors.5. You're going to survey a couple of vendors, do a search or visit your usual vendor anyway. They are redundant.And I'm sure others can think of more.
