Exciting to see! Hopefully we start to get some network effects, and start seeing communities pop up from the different parts of the internet.
One of the things I quite like about Lemmy is that a group can host their own community, and for folks who are concerned about what happened at Reddit or otherwise, the fediverse/decentralized model allows them a high degree of control, while at the same time connecting them through an entire network of people to discover them. It's pretty exciting to see this.
