Are there any websites, newsletters or RSS feeds that you could redo to read/subscribe to get the latest news about Go and everything around it? Like, not only about releases of new versions of the language itself, but also about trends around it.
Not as many as I'd like, actually, after a quick scan!
Another thing to keep in mind is that Go, as a language, is quite stable now.
There's nowhere near the amout of churn as, say, node.js.
So I don't think there are many Go-specific trends to follow
as much as there are general tech/industry trends where Go may be useful.
I have these in my RSS feeds. The one from golangweekly puts its full articles in the feed (but thier articles are links with short summaries. The other two only have summaries or maybe just links in thier feeds (I'm not sure which, as I have liferea configured to automatically follow the links.)
