I've almost entirely dropped reddit for Lemmy. I still go back to reddit for tech support and some niche communities that haven't made the jump yet. But I'd guess that my reddit usage is down 90% YOY.
I dropped Reddit and now I'm using Lemmy. I have some niche communities that I do miss as well. Until then, I'll look at forums and hopefully someone, 10 years ago, answered already a question I have today.
