I like Go because Go lets me write code and then build the structure as I go. You gotta watch out for race conditions with maps and slices, make sure you isolate things using interfaces to avoid tight coupling, the pattern of passing closures is a good way to keep the code concise and single-responsibility.

The best thing about Go is you can just dive into it. The worst thing about go is that you can just dive into it. The drowning feeling you can get sometimes when you tinker with too many pieces at once inside a concurrent system... thank Linus for Git so I don't have to restart the whole thing from scratch!
