- a "Premium Brands" toggle, that seemingly filters down to just a hand-curated list of known brands per category
- a "Top Brands" toggle, that seemingly applies some heuristic to filter out listings by companies that haven't accrued enough aggregate "experience points" (some formula like "product-listing-age times product rating", per listing?) across all their listings. Which makes it actively counterproductive to create a new random six-letter fly-by-night brand for each listing, while still allowing new brands to organically "grow into" relevance.
