(want generics? too bad! don't like the syntax for [thing]? too bad! want a framework? you're doing it wrong! want to test without using actual sending network traffic? BAM! 50 downvotes on SO for 'poor question'. Got some feedback and post it to golang nuts? HA! Prepare to be shouted out)
...but slowly we're seeing things move to a more moderate and mature state now where people are actually solving problems (like vendoring and SetDeadline()), rather than just pretending everything is ok, and building really good things with it, like go-kit.
It's just go growing up and being used seriously by people; but to be fair to the parent post, if you've used go in the past, I can see why you might have some opinions about it not being run by grown ups.
Worth having another look though. These days, it's pretty good.
There are also technical improvements (as I mentioned) and frameworks (as I mentioned). What more do you want?
Generics? No. You still can't have those.
Different syntax? No. You still can't have that.
...but maybe, now, if you go and talk to people about it, they won't flip the table about it, and you can have a conversation about it with folks on the gopher slack where everyone is reasonable and thoughtful both about legitimate concerns and future directions for change.
In my oppinion, that's a big deal...
Go has a pretty comprehensive stdlib. And a huge and growing community of 3rd party libraries. I left .NET and Java for Go around 0.9 and since then I have seen Go flower into an ecosystem I am far more productive than. The Go devs have a bias against complexity, they hate Abstract Factory Factory Singletons :P, but that does have much impact on community developed libraries. The Go community does have a strong bias towards libraries and against frameworks, but IMHO, that is generally healthy. The only concrete example of what you are talking about is the current lack of generics support.
