It’s nice how fast Lemmy is growing, but I think it is a good idea to manage expectations. In the world of free and open source software you can’t just throw money at the problem to make it better. The development of Lemmy will occur at will whenever someone feels like contributing. It’s not someones job to develop Lemmy so it isn’t guaranteed to happen at all.
Edit: Just for clarification I’m not suggesting to not donate. I’m just saying donating doesn’t guarantee development.
