Reddit still has value in niche subreddits. Do you play bass? r/bass will have conversations about techniques, beginner questions, pointers to bassists on youtube doing interesting things, etc. Think software defined radio is interesting? r/rtlsdr is the place for you. Etc.

There is a sweet spot where the subreddit has gained critical mass to sustain conversations, but haven't gotten big enough to draw in spammers and incite political arguments. There are thousands of such subreddits.
