I've started a Twitter List of those in the community working on the Go language, libraries, apps or articles:
And, oh, could we all please normalise on using the #golang hashtag please? The #go hashtag is used for too many other things — including that game that some of us love.
Not only does it offer a far better social experience, but it's interface is much better than what Google Code or bitbucket currently offer. Now, to get started with using the Git mirror, just do:
$ git clone git://github.com/tav/go.git
You can then follow the normal installation instructions to set the environment variables and then run ./all.bash inside $GOROOT/src.
Note that by default, the master branch will be checked out — if you'd rather not be on the cutting edge, then check out the release tag using:
$ git checkout release
Besides being able to track the language developments using GitHub, the main advantage of the Git mirror is that you can now use it as a git submodule within your own repositories!
This is the main reason I setup the mirror — using the wonderful hg-git plugin by Scott — but I hope it proves useful to some of you too. Let me know if it does!
