I see your point. I was maybe too quick to assume that our main site's PR will generously flow to the blog's subdirectory without much effort.

But further to MadeWillis comment, I think the subdirectory will be better suited, because the content of the blog will be quite closely related to that of our site. Our eCommerce site is about Travel in Europe, and so will be our blog. So I assume it makes sense to have them closely tied.
