There's been a couple of times in the last few years that I've looked into Reddit alternatives. My willpower to figure out a new system had never overcome the clunkiness of the alternatives. But now, given the clunk inherent in new.reddit and its first party app, I've forced myself to look into alternatives. And the alternatives are much more polished and active than they were before. Obviously I have to grant a bit of leeway to these nascent sites, but it really does feel like the internet back around 2005-2012. In fact, it's brought up a bit of nostalgia on my part and some re-evaluation of whether endlessly scrolling Reddit (or anything really) actually made a positive impact to my life.
I've forced myself to use Kbin, Lemmy and Mastodon, and ventured over to Tildes and Bluesky as well. It's exciting to see so many promising alternatives to Reddit. The userbases are also very manageable. I don't feel like I'm typing in the void, but still feel like there are enough people to have a good variety of voices.
All that said, I'll still use old.reddit for some niche communities, but will try to be more and more active in the alternatives.
