I’d say that its very subjective to the editors also. I noticed that some of my places were deemed not unusual while they are quite weird for EU but maybe not for US. While a lot of EU countries have very mainstream tourist attractions on the atlas. Like Stockholm has the Vasa museum and Skansen, the two most visited places in the city and on every travel guide ever, but the official santa village in Rovaniemi was not deemed interesting. (which I still disagree with. :P)
Not saying that we should remove anything or be more strict, but maybe be less strict even? Apart from the few super popular holiday destinations (London, Paris, Brussels, Amsterdam, Berlin, etc.) most people know nothing about most cities and having the ‘more well known’ attractions on the atlas could convince them to go there in the first place.
Like sure once you google Rovaniemi you find the santa village, but why would you ever google Rovaniemi? Who has even ever heard of that place? You need to stumble across it on the net, get interested and go. So maybe don’t put on the Eiffel tower, or the Big ben, but why not culture palace in Warsaw? Or the Opera house in Prague? etc.
I added a lot of stuff to Leiden, NL and Stockholm and anyone who visits either cities can now have a pretty fun tour across all of them. I think that it helps. It certainly does for me!
