We can be picky, but with good reason as security is an exact science and a costly one to get wrong. There's so much conflicting and out right bad advice posted online these days that sometimes it takes a picky community to help clarify the best practices.

For what it's worth, some of the advice given in that article was worth mentioning (eg fail2ban, it's a great tool). But the shared account suggestion was the complete opposite of how you should be managing user accounts as you lose audit trails. And for that comment alone, I'd recommend people read that article with a degree of scepticism before rushing onto any boxes they might administrate.

That article has generated a lot of good discussion though. So even if just indirectly, it's been a valuable contribution to HN.
