I'm sorry to hear that. We really strive to talk to everyone we can, and we are happy to hear all the stories from subscribers, or otherwise. Feedback, and more importantly, meeting with people is why we go to conferences.
Can you please remember at which GopherCon / year this happened?
I'm usually part of all the conferences teams and I can say that at conferences such as GopherCon US 2019, I speak daily with 200-300 people easily at the booth.
All of our booth staff is developers + myself (Developer Advocate) and from time to time we are joined by our Product Marketing Manager.
It's not an excuse for this type of reply, and I believe that nobody should be treated like this.
You can disable the indexing of the whole GOPATH as of 2018.1 and it will finish indexing a whole lot faster. See Settings | Go | GOPATH | Index entire GOPATH.
Excellent read about Go Assembly and how to use it. I'd love to see more on this, especially since assembly isn't something that often used, but after reading your post I can appreciate the overhead of having to maintain it in the future.
Thank you for the time put in the post about this.
We are working on it, stay tuned :)
