For me the ability to use packages made by other people is a draw card for a language. However, when I first went to the site, all I could think was "Whats a crate in relation to programming or more specifically Rust? Is it Rust's idea of a package (eg like ruby gems)." I just think it would be good to have the site say Cargo: The Rust language package manager. The site also says this: "The Rust community's crate host". Is it not a cargo host for distribution of crates where crates are Rust packages? Is there non-community crate hosts?
