From the Roman Martyrology: January 29th (Patron Saint of Catholic Bloggers)

"St. Francis de Sales, Bishop of Geneva, Confessor and Doctor of the Church, the special patron with God of all Catholic writers who explain, propagate or defend Christian Doctrine by publishing newspapers or other journals in their mother tongue.  He departed to heaven on December 28, but his feast is specially observed on this day because of the translation of his body."
