As I mentioned in later comments, my first impression was nothing more than a first impression. When I learned that it was not just some random person that threw up an instance but some respected mods I circled back and had a closer look. And at a closer look, I admit that my first impression was wrong, it seems like a quite well managed instance with great potential. I actually created an account that to evaluate that, to see where I finally will end up when the dust have settled. So thanks for your effort, and sorry for my poor first impressions. But it really doesn’t matter what I think, what matters is where the prominent rust front figures choose to hang out, I hope that will include one of the lemmy forums.

But the thing that will decide this is where the leaders and contributors to rust will choose to post their updates, and take their discussions. So, for now I guess lurkers and regular users will have to follow all and see where this will be.

My impression is that it is just someone who created a community for each language they could think of. But if programming.dev is a popular instance that is well managed, then sure. But for now, it seems that lemmyrs.org have more users and momentum.

EDIT: On a closer look, it turns out my first impression was quite wrong. programming.dev seem like a quite well managed place, so I do not have anything against using that as a base for rust if that is what the rust community chooses.
