Hello! Being the author of the blog post commented here, I'm glad it became food for thoughts.

Here a few of the salient points:

> They are not cathedrals!

True! As I learned after writing the blog post, a Cathedral is not simply a large church. As written in several comments there has to be a bishop.

> Fallacy of using other projection than the Mercator one.

It was known that they are "visually" aligned on the Mercator projection. The question is: does it mean that they are aligned on the surface of the earth? That question was the crucial one underpinned the post.

> Birthday paradox and Texas sharpshooter fallacy.

These are two really interesting take on the problem that I did not considered or knew about. Certainly worth exploring in a next blog post.

Also I have to inform you that the blog is temporarily suspended. This decision is after an unfortunate billing policy from the provider netlify. It has nothing to do with the comments received here. On the contrary the comments received here had encouraged me to write more (and to document myself better beforehand).

I hope to be able to bring it up back soon with a different provider, that would not add extra costs with no capping for going "viral" and exceeding the allowed free bandwidth.
