Yes, clearly being able to keep your blog running when it's on the HN homepage is NOT one of necessaries.
Touché
It's a classic WP mistake to not turn on one of the WP cache plugins (WP Super Cache, for instance). It's less about knowing scalability and more about just ever thinking whether your blog can have more than your 6 friends visiting it.
Thanks! Installed. 6 friends?? You must be an extrovert.
Haha you’re welcome. Every Wordpress user does this at least once.
