I've been using Go for various things for quite a while now. I do love the language. If I would use it for any serious large scale project? Perhaps not just yet. There are still some wrinkles that need ironing out. Most notably: Go's GC.

These 'wrinkles' are not fundamental problems with the language though, and most are on the slate for fixing, so it's just a matter of time for Go to be ready for anything. Development pace is still quite furious and improvements are coming out every week.

In the meantime, I thoroughly enjoy using it for smaller tools and assorted bits and bobs. It's a very pleasant language to work with.
