Rel=shortlink – url shortening that really doesn't hurt the internet

Short links are intended to be transient. They're used in environments meant to be transient (tweets, emails, phone text messages etc.).

No, we don't need to hoard every single tweet into eternity because someone said so. Let them go. Let them fade away. They want to fade away. We need that space for another fresh batch of trillion tweets with short links in them.

This entire drama around everyone having their own short link server because-what-if-bit.ly-goes-down is just an example of developers having too much free time on their hands.

If you want your link to have durability - don't shorten it. Simple, right?
