Think its going to be hard to gauge or get responses on HN, because of the tremendous amount of animosity and trolling from competitors and detractors the language has previously received on here. This can be seen or realized from past threads. Many V supporters are less likely to come here and get engaged in more battles, while supporters of other languages don't have to go through that or to that extent. Mentioning Go, even if innocently, can come across as a setup for another language war thread.

In terms of usage, maybe some places you can get metrics on this are below. You can also do comparisons between languages:

Personally, I have experimented with V, along with other newer languages. Have found it quite useful for IT related tasks and like it. As the language is in beta, don't use it for anything critical (yet), but non-critical and fun. Probably it would be good to ask on their GitHub, as they are one of the languages that have open discussions.
