It seems the Pope has a fast-growing Twitter following to his account in Latin
He tweets is 8 other languages too, but (like reintroduction of Latin Mass?) it seems this dead language won't actually die out, and the tweets are comprehensible to speakers of many languages with a passing acquaintance with Church Latin.
Here's an example: Movet saeculum ut nos opesque nostras et respiciamus voluptates. Monet Evangelium caeteris ut recludamus nos cum egenisque nostra partiamur.
