mainstream, the conversion of the edge to the middle of the pack, of the rare to the commonplace, the fringe to the popular, and you always lose something, something that made the fringe the fringe, when actually nothing of content changes, but the fringe is the source of the content, so when the fringe became the mainstream, it begins to lack what made it mainstream in the first place, but to remain in a niche, in a box, label, and shifted among the store shelves, from the only one in the back row, to multitudes of copycats with prime shelf location, then back to the bargain bin, before going back to the back row, all alone, with the rare, occasional, fringe shopper seeking you out and buying. something to be said for consistency.
