I've found the YouTube algorithm pretty good for finding new stuff (done pretty well at recommending post-punk stuff to me recently), but also radio stations. Most of the good ones are online, but BBC 6music has some really good shows for discovering both new bands and older stuff you never ran into. Iggy Pop goes for particularly deep cuts of niche genres, so tends to be interesting even if you're never going to listen to any of it again.
