Here is an article in the Miami Herald that mentions some notable Catholic bloggers in a Lenten theme. The online version though leaves something to be desired since they inserted spaces in URL names. They mentioned that Peter Nixon regularly gives up blogging in Lent, though he actually stopped blogging last year in May and even sillier they put up the URL for a totally different Peter Nixon who also runs a supermodel site. They discussed Catholic Ragemonkey but made it sound like it was run by only one priest just for the purpose of posting homilies.
Interestingly there was also another shorter article in same paper in a different section called Blogging for God. This one mentions only a couple blogs, but this time information on Catholic Ragemonkey is correct.
