This is not the worst idea I have heard. I think it would be really cool if people could get local instances going for their cities. Then have the communities be based on topics relating to said city.
I gave up hope when I learned that the blue and green recycle bins in my area are really only there to make the consumer feel better about how much we waste as a society. A lot of the stuff we put in those bins still just winds up in a landfill.
How much power does it take to run an instance? Not planning on hosting my own, just curious. I read stories about people being able to host a Mastodon instance on a Raspberry Pi.
Maybe I'm misinterpreting your post but what's the point of having an instance if your only users are the mods you appoint? You'd just be creating your own personal echo chamber. The whole point of a site like this, at least as I see it, is to bring in a wide variety of users with different opinions. That's a big reason why Reddit was so successful in the early days. I know that everyone is anti-Threads and Meta, but clearly @ruud@ruud@lemmy.world knows something we don't. I think being federated with Threads could be a good chance to grow this community and bring more attention to the Fediverse as a whole. If you see something from a Threads instance that you really don't like, you can always block and/or mute the account. On Mastodon, you can block entire instances from showing up in your feed. I'm not sure if that is a thing with Lemmy or not, but if not, it might not be a bad thing to implement later on. Sorry for the wall of text.
After something like this, the users need reassurance their data is safe, or at very least not severely compromised. This is not a good mark on the sites reputation in these early days.
Never too old to learn a musical instrument. You can pick up an acoustic guitar for cheap at a pawn shop.
Learning how to code is a good one that can be done either free or very cheaply and doesn't require a lot of computing power when starting out. All you need is a text editor and Google.
It is a really well made game. I had a lot of fun playing it. There is also a regular SuperTux based on the original Mario Bros.
