I don't think compliments are a good way to interact with strangers. Better is asking for the way to ..., most important thing is to follow your intuition.

Obama talked to strangers too. He wrote in his biography that this was a thing that he missed when he was a president ("random chat with a stranger on the sidewalk").

I think you can subsume this under being more worldly, but talking to strangers means it gets a lot harder to become really ideological/partisan and looking down to other people.

Large organizations sometimes use Strongswan bc it has stuff like CAs integrated. (Ok, it's using IPsec, but that's still not OpenVPN)
