Honestly I'd just ask if they'd like to talk about whatever "small talk" topic I'd want to know more about. To me it seems like a fair way to ask if they're open to conversation and then ask specifically about what I'd like to know. If they'd rather not talk I wouldn't be offended (though I'd probably be a bit disappointed for a little bit).
Assuming this is re: the article about the Finns you posted. I understand the logic behind not wanting to bother people as I do that myself, so I wouldn't want to force someone to chat if they don't want to.
