I have it set to three issues a day, and when I started recognizing old ones I lost interest.
I'm really good at remembering whether I've seen something before. 
Though... I'm sure that if I were to radically alter the government I'd get a lot of new issues...
Ah, I'm only getting one issue each working day. I don't go there daily, but at least once a week, so they won't have to stop sending me issues because I already have five.
I don't think the type of nation alters the kind if issues you get. I think 'it's 'one issue fits all'.
