For instance, I use to: redirect new reddit site to old.reddit.com

I keep a blog on wordpress.com, but I really dislike their new blog admin interface, but the interface one can still be accessed , so I redirect to there to edit my posts on the old interface

I use some alternative front-ends, like imginn.com, which is alternative front-end to instagram, so I set to redirect links there.

This sort of thing.

Mobile Wikipedia to normal Wikipedia.

Redirects from translated versions of Google or Microsoft documentation to the English one. The Microsoft ones are okay-ish but I strongly prefer reading the original version. And the Google ones are a patchwork of machine-translated nonsense, "powered by Google Cloud Translation API"
