Seems to me the fear of overloading one instance over another will not happen after all.
But I do hope the Threadiverse can hit 500,000 consistent active users by the end of summer.
Give me that hopium guys! 💉
Have you checked out kbin? It has some of those features, and you can sub to lemmy communities with it. It also allows you to follow users, which lemmy doesn’t seem to do. But you can’t save posts at kbin, which is something I use a lot.
Edit: literally just discovered you can save comments and posts, at least here. I don’t know if that’s new or if I missed it somehow.
