'go get github/user/project && cd $GOPATH/github/user/project'.
And to avoid dependency issues, I use one of the many vendoring tools. Currently 'govend'.
That's the issue, and it's a big design flaw - do away with this GOPATH
I don't have go/src/ checked in. Is that what you mean? If you do that, you are doing it wrong. I have many, many go/src/$org/$project directories, each of them have their own source control (most of which is different git repos). If I am working on my stuff, cd $GOPATH/src/github.com/sethgrid/$project. That is the repo under source control. Do any development I want, push up any changes to that repo. Rinse and repeat. I can then cd $GOPATH/src/github.com/sethgrid/$project2 and do the same. When I want to pull down $project3, I just `go get github.com/sethgrid/$project3` or manually clone it and I can cd over to it and work on it separately.
Maybe I'm not understanding your criticism.
