A Hong Kong Chinese lady suggested the Pope to run a blog to promote the Word of God.
A Holy Blog of Obligation!!!
The post from Fr. Tim Finigan is fun to read.
Fr. Z is from Rome, and his blog on liturgical issues is the most popular Catholic blog. If one of the high profile Bishops from the Roman Curia started a Scriptural blog, I think it will have a good number of faithful audience as well.
But I don't think it is a good idea for the Pope to run a blog. Because it would be too popular, and too many people would try to get into the blog. And for sure, the server will crash!!!
