I'm not poly (though sometimes I'd like to be), but since this the internet, I'll spout my opinion anyway.

The poly crowd defines "swinging" as sex as parties with people you barely know, while poly people are all about the relationships.

My impression about swingers though is that many "date" other couples on a regular basis, so there is some sort of relationship that develops. And I'd find it hard to believe that people who call themselves "poly" never on occasion hook up sexually with people they think are hot.

So I bet in reality there is a bit of overlap.
