Because I seem to spend so much time in Brussels, and also have lived in several cities which until now have only been tags …
Berlin, Brussels, Zürich, Vienna, Guangzhou, Taipei, Adelaide, Melbourne. Countries also. How does living in Switzerland or Germany differ from the city within which I reside? Or rather, how does it differ here, where I write?
Because there’s no way to make things neat, to allocate everything according to its place; categories, tags, uses, definitions change over time and even from post to post, I decided to stick with the cities I lived in as sub-categories for the Places category. Countries, other cities I have spent time in or have a connection to have remained free-floating.
Another way to regard the issue: these cities should have been categories all along, and by making them so now, I’m merely anticipating the addition of new cities (or places) in which I shall reside.
Anyway, more importantly, it makes it easy to see where I (will) (might) (have) be(en). There, in the sidebar.
