People have to be willing to give things a try, so I think it will definitely grow. I was never a Reddit user, I tried this on a whim, just to try and have conversations with different people. The one good thing is that there are many functional apps, and you will only see things you are interested in, and when you don't, you down vote it.
But ultimately it's still the same echo chamber that all social media is, but without ads.
I never used Reddit so I cannot comment on that, but I have tried a few Lemmy apps, I think Boost is the favorite one, it shows avatars and such and I actually get notifications. Many other Fediverse apps don't for whatever reason - Pixelfed being #1. The only difficulty I have is replying to a picture comment.
Maybe Reddit owns the "Rights" to that style, who knows.
I try to use nothing Google on my phone, which I know is impossible, but I try. The only thing I use is the maps - sparingly - I prefer Here We Go, and whatever Google stuff you need to make apps go.
Key Mapper a few Android versions ago would have been the solution, but in 14, they definitely scaled back what you can do. It almost like they are becoming apple. Lol
I never had one.
