Hi, I'm looking for some help from developers who write Cargo packages. My research group is interested in the different choices new package managers and repositories are making when designing their ecosystems -- e.g. Rust/Cargo, go, and Node.js/NPM are all relatively recent, but have made some pretty different design choices; they also differ wildly from some ancient package systems like CPAN. We'd like to know what the impact of those design choices are on how you negotiate breaking changes among Cargo package developers, and what you think the platform's design is trying to accomplish.
Could I ask people to take ~20 minutes of your time and fill out our survey at How Ecosystem Cultures Differ (Survey Results)? I'll report back here when we've analyzed the results (or there's a sign up link to be notified when results are out at http://breakingapis.org).
(If you don't use cargo, but do use NPM, CPAN, Hackage, or something else, we're still interested -- just make a different "software ecosystem" choice on the first page. The study is a comparison among ecosystems; Rust/Cargo is one point of comparison).
