Reddit is fine but like with most things, we mis-use it. We're doing it wrong. And reddit loves it and encourages it, because... money.
Generic subreddits are one of the problems with reddit. The niche subreddits are good, probably even awesome, at least in my opinion. The users are usually friendly and will help you. Searching for answers about specific things may also work.

The biggest problem I have with it, is actually not its fault. It's a problem with the internet as a whole. It's the almost disappearance of RSS, at least as a culture.
I used to have a centralized place to get my news, the news that I want to get, based on what I like, curated by me.
But is has shifted to a company-backed and algorithm-based mechanism where you either don't decide what you want to get and/or you get lost on the platform in the many ways it persuades you to consume what it wants.
And it's very difficult to get out once you're in.
Recently, I've set up a private miniflux instance (an RSS feed reader) and I'm loving it. Problem is, I'm hooked on reddit. I am. I'm strongly trying to moderate it, but it's very difficult.
It's another reason why I'm on the smolweb. This is fun. And hopeful not mindless. Or at least not capitalistically or algorithmically or popularistically mindless.
