There's another factor too: Steam just plain doesn't change the store that much. When I open the Steam store to browse, I bypass literally everything to scroll to the bottom of the page. There I will find a few tabbed lists. One will show me new and "trending" games (I have no idea what they consider trending), one will show me the current top selling games, and another will show me upcoming games that are receiving hype. I rarely ever view anything else on that page unless they're running a seasonal sale.
