I use gopkg.in. Personally I would like to see the community avoid adding more to the 'go' tool. It is already doing too much. I think the solution provided by gopkg.in is better than other more conventional methods (e.g. npm or maven like). I love Go. But it is ironic that 'go fmt' was designed in from the beginning. And now we are still dealing with semver and package dependencies. I went with gopkg.in because it made the dependencies a non issue from the tooling point of view. It is made possible by having 'import' direct from the repositories, which archive different versions and tags. Perfect for something like gopkg.in. I am probably in the minority.
