At the moment a lot of new people come to /mu/ having not listened to or actively sought out new music, and the people of /mu/ are way too keen to spoonfeed them by giving them so many recommendations. The end result is thread after thread of "give me ambient recs" or "what's some good indie pop /mu/" followed by lists of albums from people keen to pitch some of their favourites but ultimately ending up filler, dead posts. What's more, a lot of the recs are /mu/ approved or point towards so-called "/mu/core" charts and these newfags end up piling into the same stuff discussed to death and restricting the variety of discussion on the board.
Why do people allow this? Where is the incentive to encourage people to go to Last.fm or RYM and discover music for themselves? For instance /a/ are stalwarts in shutting down people who ask for recs because of how low-quality the thread becomes and, most importantly, how it propagates the idea that they will be able to return to the board to mindlessly ask for even more spoonfeeding. If people were directed to the means of discovering music based on their own preferences (which, with new people, are far more expansive than people who have settled into /mu/'s nook) we'd have a much more diverse board culture.
It's not just about board culture, either - I can't be the only one who doesn't want /mu/ to devolve into a pulsating blob of album names for clueless fools to leech from. We need to direct people to the sticky in each rec thread, not satisfy them and tell them that it's okay to not do the work yourself.
