> Instead of a search, you need to present me with a shotgun blast of examples of things to like; getting the initial data out of me that you need to be useful needs to be twitch-simple, and ideally game-mechanic (have some kind of scoring, level-up system, and leaderboard for how many and what kinds of things I've reviewed).
