Reddit, imo, is a joke for the simple(ton) reason that 90+% of new posts are nothing more than stupid questions. I created an acct. for the sole purpose of filtering the garbage, which apparently is the majority of the content.
Used to be all over reddit, but now I only check r/boardgames with any regularity. As the other person who replied to you said, the niche subreddits aren't too bad, but the main subreddits attract no end of stupid comments.
It depends entirely on what subreddits you read. The technology based ones are usually OK, as the niche ones. The more mainstream ones are pretty crap.
