To be totally honest I'd say the comment is verging on toxicity. They're basically telling these backend engineers to piss off and save the blog post until the mobile site loads faster. It's quite likely they have little-to-no control over the mobile site and caching improvements are one of the few indirect ways they can improve it. This exactly the opposite of what we should see in response to content like this.
That's not really what I'm going for. The way they framed the blogpost just lacks perspective. Perhaps that's due to organizational structure, but maybe there's a lesson in that too.
I am a little disappointed I ended up as the top comment. The technical comments are more interesting. The upvotes on my comment probably just represent frustration.
You can easily open up the front page of HN as a logged in user and see that it contains information about which storeies you've voted for and which you've flagged. On top of that, you can click "hide" to hide stories. These will only be hidden for your specific account, not for every person who loads the front page.
What's more, the go-to call-to-action by HN admins during really popular stories is to have people log out, because logged in users don't get cached results. Have a look at the comment by HN admin dang on the Trump winning story. [1] The key part being "please log out to read HN today, unless you want to comment. Then we can serve you from cache".
They're two completely different operations, with completely different complexities behind them.
The "hide" feature is not analogous to what reddit is doing.
When I go to reddit.com, I see a list of stories from subreddits I've personally selected.
