I thought the same, once. It's a hugely popular site so the noise is in accordance with the scale. Once you move past the frontline subs into those that don't allow circlejerk/sh*tposting there's an abundance of information. Tech, health, finance, legal, photography, travel, real estate, farming, crafts, woodworking, cooking, and on and on and on. Just about as far as your imagination can go, there's most likely a subreddit dedicated to just that. It just takes time to learn the ins and outs, and YMMV because the mods are the ones that largely determine the quality of the subreddit in question.
One easy example:
r/gaming is 95% garbage.
r/games and r/pcgaming are by far better.
Adjust your filters and absorb what's worth absorbing.
