It gets pretty tiring on HN/reddit to watch people demand so much shit for free, namely other people's time. If you've ever run a project with users (most people haven't), you've experienced these demands first-hand.
It's nice to read these sorts of posts when it's getting you down.
For me it was the recent outrage at Elm's creator. Random people on HN/reddit basically acting like they were some disgruntled paying customer. You can see a common thread with Rich's defense of Clojure.
Some people see this and go "okay, I'm fine with this, I like Evan's vision and I want to see where this is going"; many of them use Elm in production and accept the occasional bumps in the road.
Others are interested, and happy to watch from afar, but are waiting for Elm to hit some form of 1.0 release or otherwise announce that it's ready to be used in production before making the jump. (I'm in this camp; Elm is clearly not suitable for me today, and that's fine!)
And some take the entire thing as a personal affront. Entitlement is an issue across all of open source, but Elm has some characteristics that makes it especially prone to driving a certain type of user wild. How dare Evan change Elm internals in a way that breaks the way they were using Elm?
