There were a lot of good suggestions about people I should have added to the list. And I learned a lot about Google in the mean time, that it is not a simple computer generated type of search. It is regional-specific, a great deal depends upon what exactly you include and exclude in the search, etc. Nevertheless, we can still conclude a few things. What I was after was an answer to the question: how do we Catholics 'idolize'?
I don't want to sound mean here, but, for instance, for as gifted as he is, there are greater Catholic biblical exegetes at work in the field today, so why is Scott Hahn so well known? There are certainly more ingenious interpreters of the Theology of the Body than Christopher West around today, so why is he synonymous with the field in the popular imagination? (Incidentally, Christopher West Theology of the Body generates 199,000 results.) Off the top of my head, it's not about genius, it's about presentation.
But I knew all of this before I did this little experiment. So what did I learn?
1. The top-ranked are those well known in the secular world.
2. The internet is not clericalist. Clerics rank high, but not disproportionately so. There is a strong showing from the laity.
3. There is a strong showing of intellectuals, especially when we stretch out to the fifty year mark.
