Before I read the article; why does the permalink symbol looks exactly like the infinity symbol (∞)?

[arscan]

Because it is an infinity symbol (U+221E).

I guess the idea is that the permalink will last for an infinite amount of time. I personally think its pretty clever.

I guess it's because this is what a permalink really is: an URL meant to last forever (hence the infinity symbol).

because it is?
