This system is unusual. I think it works, have already observed a couple moments of people revealing very personal things that happened three years or three decades ago, and the comments make it clear that people here "know" each other.
But the store? Just because I haven't seen it doesn't mean it doesn't exist! I find new little wrinkles on YLF tech all the time. One of these days I might even find a list of acronyms and terms explained. But I haven't seen a store. It is clear that the blog was much more tied to plugging products in the early years than now. Did the store go away with that?
