Even if things are not directly "listening" and then directly serving ads (and I don't even think it's a crackpot theory, we KNOW companies would LOVE to do this), then we can surmise that at least the following happens: - Ad networks have figured out who my closest circle is and has location tracking non-stop. - I talk to my friends about something "which is taller, space needle or empire state building?" - Even just one of them searches this. The ad network ties their search to me and ties "empire state -> NY -> NY trips" to me - I get ads for trips to New York
