I started filling this out with a bunch of go tutorials but then I found the official go resources page. Should we just link to this page rather than curating our own? It has the majority of the tutorials I was going to link. https://github.com/golang/go/wiki/Learn

Definitely could have that as one of the resources (possibly duplicated for each level). The idea behind the command is if there's anything beyond "official docs", that really spoke to you. Although i suppose golang is probably, uh, "more well defined" than JS

One of the things that is missing from the "Learn" list is inspiration. I've found that finding good sources of inspiration has helped just as much as formal learning resources.

The other source of resources that I've seen pop-up every now and again is the Awesome Go list:

I would love to take this if no one has indicated any interest?

Go (🎉 ) for it, @peoray
If in doubt of what should go in as resources, check in with @billglover and @cbelsole

When I tried to run greetbot in my test-slack, it shows this error
Darn - that slash command didn't work (error message: 404_client_error). Manage the command at greetbot. @stain88

Still having issues
