Basically using a redirector plugin with a rewrite rule for twitter URL's to be translated to nitter.

Over the months I accumulated quite a few little, useful rules. (Like stripping out the highlight text thingie that google "helpfully" adds when clicking on search results.) I can post a few once I get home.

I like to do as much as I can with as few plugins as possible, which is why I don't have a dedicated plugin for that.
