Perhaps more proof of work is necessary, but it makes me sad.
I still remember creating my HN account. It stands out in my memory, because it was the smoothest, simplest, easiest, and quickest account creation of my life.
I had lurked here for around a decade before finally creating an account. Any urge to participate was thwarted by my resistance toward creating accounts (I just hate account creation for some reason). But HN's account creation process was a breath of fresh air. "You mean it can be this easy? Why isn't it this easy everywhere? If I had known how simple it was, I would have created an HN account years earlier, lol."
It was especially stunning to me, because I think the discourse on HN is generally of a higher quality than most other sites (which I wouldn't naturally associate with such an easy account creation process).
It's my only fond memory of account creation (along with maybe when I created an account on America-Online back in the 90s, since that was my first ever account and it was all so novel). Just a few quick seconds, and then I'm already commenting on HN. It was beautiful. I remain delighted.
