I understand that some folks like the way it works. I still wouldn't do it. The short meeting with a chat is fine. Were I to be asked on a date with somebody along whom I'm not interested in dating, I'd pass on that and likely on anything further. That doesn't work for me.
When speaking of various forms of non-monogamy...it ain't poly if you're just fucking around.
While polyamory, open relationships, and swinging are all distinctly different approaches to non-monogamy, they are not mutually exlusive. Folks can, and some do, engage in more than one of them at a time--and it's all good.
