It feels like a bit of an unpopular opinion, but I agree - I was definitely more of a lurker on reddit than a massive contributor (14 years, <30k karma), but I loved how there was always a relevant subreddit for even fairly niche interests. I miss that on the fediverse - but at the same time, I'm hopeful that the fediverse will, in time, gain wider attention. I don't miss the low quality content, but I miss the sheer volume of content, and with careful curation of subreddits, managing the signal to noise ratio was easy enough.
