I think the best way to learn about what is good or not is through the opinions of people you respect or agree with enough to take their word for it.<p>Centralized example: Yahtzee Croshaw of the Zero Punctuation video game reviews eschews any semblance of a ratings system because it&#x27;s a little absurd to boil down a complex opinion into a number. Watch a review and get a sense of whether you&#x27;d like the game or not.<p>Decentralized example: plug.dj (before it went down. Dubtract.fm kinda sucks) let users get in line to play one song for a room. Some rooms can have you waiting 3 hours to play <i>one song</i> so if you&#x27;re gonna wait that long you&#x27;re gonna play a banger.<p>Yeah it&#x27;s more effort than a numeric ratings system but you get what you pay for with your time.
