Phil at Brandywine Books suggests that St. Thomas might have blogged the Compendium Theologiae himself, had blogging been invented in his day. To which I respond:

It would seem that, if St. Thomas Aquinas were alive today he would be a blogger. On the contrary, St. Thomas could not possibly have written so many great works of philosophy and theology had he spent his time at the keyboard. I answer that St. Thomas would have had a collection of bloggers with laptops close to hand at all times, to whom he would have dictated blog posts in round-robin fashion, in between dictating paragraphs of the Summa Contra Gentiles and the like.
