The number of "replies" on "3 reasons why you hate poland" is more than that of "Why do you love poland?"
If someone likes a restaurant or shop, they tell on average 3 people. If they hate it they tell 20.
And the number of posts isn't a fair indicator. Somebody writes the three reasons they love Poland, and a couple of people reply to say, that indeed yes, they like the same things. Somebody posts the three reasons they hate Poland and people are arguing for days about it.
Also a lot of people here are expats or immigrants. It would be rude to moan to their Polish friends, in-laws etc about Poland's shortcomings. So doing it here is a good alternative.
explain why the simple concept of picking up after your pooch is so difficult for people here to understand
Why indeed. The filthy stuff is everywhere. I heard about a lady in Belgium who got so sick of it in her street that she bought some little Belgian flags, on cocktail sticks, and stuck one into each turd. Within a day her street was clean and the neighbours started to be more careful.
Polish flags are easy to find - it might work here, if anyone can face doing it.
