I brought on an additional admin to help me out. This site will last. In fact, I'm working on a massive improvement to the Lemmy space. I have several volunteers from Lemmy.world helping out, too. It'll make many of your points less concerning once it launches in about a month. I'm not quite ready to share to a broad audience what it is.

That is a fair point about the searching and ease of use. It would have made sense if people spread their communities around more; however, everything is in one place, so why not go to that one place? Everyone is either self-financed or earning through donations. I assume some of the instances won't last.

I have a desire to grow. I bought ads on YouTube and other services to try to gain traffic. The problem is communities don't want to be on more minor instances, and people follow communities. There isn't much I can do about it. I've tried to create interactive communities and find mods to grow them, but it's not working. I plan to keep running it; I'm excited about what I will bring to the community. I want to see it all succeed.
