Hrm, I don't consider this post to be insulting. It's a valid concern. Why do you think it's insulting?
We will eventually have an official package repository, but the idea behind Nimble's design is to be decentralised at its core, the official repo will just be another mirror for packages. Nimble uses Git/Hg so you can install from any Git or Mercurial URL. On GitHub, if you want to be sure that a package doesn't disappear, just fork it.
