URL shorteners are nothing new, Tiny URL has been around for 100 years, but WP.me is different in a few ways:
- WP.me is the only two-letter .me domain in the world.
- Every blog and post on WordPress.com has a WP.me URL now.
- These are all exposed in the <head> using rel=shortlink.
- It doesn’t work for any URL in the world, just WP.com-hosted ones.
- The links are permanent, they will work as long as WordPress.com is around.
- WP.me is spam-free, because we are constantly monitoring and removing spam from WP.com.
