Looking at your posts, it seems like you’re really into ecology/farming/wildlife. I think Lemmy is currently seeing the biggest growth with its tech and tech-adjacent communities. Whether it’s because it’s a little more complex to use or because that’s just the demographic that knows about it more, I can’t say for sure.
It reminds me of the earlier days of Reddit (which I didn’t even participate in), when it was almost solely a programming/tech community. As it grew in users, so did the variety of communities. I think Lemmy is going to be similar.
I applaud you for building up the communities you’re a part of. I hope that you can look back in a few years and realize that you sowed the seeds for something that grew much bigger.
