I tend to pay attention to labels and follow the ones I like through various sources (label website, Soundcloud). Labels curate content of similar themes / genres. Some examples: Ninja Tune, Warp, Brainfeeder, Matador.
I do this also, following a few labels I really like (Never Say Die, Dim Mak, OWSLA, Monstercat, RAM Records, etc). I follow quite a few artists on social media as well.
