Do acronyms such as YOLO, LOL, and OMG drive you crazy? Perhaps you'd rather not see a particular slur in your internet browsing? If you're a Chrome user the extension In My Words has you covered; it will replace any word or acronym you hate with your preferred word when using Chrome.
Of course there are probably a lot of interesting alternative uses for this extension, especially during this political campaign season. I think I'll go replace all the candidate last names with names of the dwarves in The Hobbit.
