> In my country

I often see people here referring to their country without mentioning the actual country, i.e. they hide the interesting detail, which I find weird. Why not to write "in Iceland..." instead? Or is it a privacy thing or just some kind of modesty?

Because very often, any time anybody mentions their country it is quickly dismissed as "not applicable, because nobody but OP lives there".
