Seconding this. If you remove the '-3' at the end, it redirects back to the URL above. Cheeky, I like it.

Doesn't actually seem to be an intentional redirect, though—if you truncate everything past the "b" in the URL, it still works (and similarly for other blog posts). I have a feeling it's just doing a "best match" based on the URL.

That's just Wordpress. It is just doing a closest match on the slug.

Also works if you remove 'eta-late-than-never-3'.
