Dear Mr. Goldberg,
This may interest you; this is the latest decree from the Pope, accessible on http://www.vatican.va/latest/latest_en.htm. Itโ€™s a speech on mass media and information technology in the 21st century. Anyways, though he does not specifically mention blogs, these two paragraphs certainly seem to be pointing that way:
In the first place, a vast work of formation is needed to assure that the mass media be known and used intelligently and appropriately. The new vocabulary they introduce into society modifies both learning processes and the quality of human relations, so that, without proper formation, these media run the risk of manipulating and heavily conditioning, rather than serving people. This is especially true for young people, who show a natural propensity towards technological innovations, and as such are in even greater need of education in the responsible and critical use of the media. In the second place, I would like to recall our attention to the subject of media access, and of co-responsible participation in their administration. If the communications media are a good destined for all humanity, then ever-new means must be found โ€“ including recourse to opportune legislative measures โ€“ to make possible a true participation in their management by all. The culture of co-responsibility must be nurtured.
