If you look for the stream of articles that invaded HN in the last weeks, it is usually because someone implemented a web site in Ruby or Python and when it gets scalability problems all is heaven on earth with Go.

Of course if you're doing server side development already with more performant languages and runtimes, there is little incentive.

Or you could use a caching strategy, like enabling cache in apache.

That would work as well, yes.

Why would anyone senselessly troll HN?

It as a serious question. I spent a few minutes looking into Go and could find little reason for it. So wondered what the use case was.
