go is asymptotically approaching boring and that's one of the goals of its creators. let other new programming language stars shine: i'd like to see the niche rust settles in for example, and that needs code.
Go is a general purpose language and people write many different kinds of programs in it: from command-line utilities to network tools like web servers and proxies and file servers to distributed databases to website backends.
As long as you keep calling it "niche" I guess we do need those kinds of articles.
I would love to see more of these stories but not just for Go, pretty much for anything under the sun, especially "old and boring" languages and technologies. I want to know in which situations people still choose C++ or even C for new projects today, I want to see who's using Pascal (and what for?), I want to see if anyone is dumping, say, Postgres in favor for Oracle.
At my previous job (Rackspace) I had the awesome unexpected benefit of sitting on sales calls with our enterprise team, listening to what well-known tech companies are doing "under the hood" and what problems they're facing and what solutions they're considering. On a number of occasions I've heard folks say "this is super, you should blog about it", so I say: the more the better!
It's just another opportunity to learn, not about "fluffing"
It's very easy to pick up, though, especially if you played with Turbo Pascal as a child.
What's the niche?
that said, i use go for everything. although most of the go code I've written has been in end-user applications, tools, and services, I still open up a listening port on localhost and serve web pages for any visualizations that i need to present. get the job done in the most boring way possible. that's its niche.
