To be fair to the hosts of Multiamory, it was a stupid source of inspiration but they renamed it to RADAR pretty quickly (I forget the acronym lol). A big part of the idea is scheduling regular check-ins with people so that you can discuss anything you need to in a format that’s comfortable, instead of “hey, can we talk?” whenever something is wrong, or worse - bottling it up and holding grudges or bringing it out as ammo in an unrelated argument.

Their politics really aren’t that bad - generally a vague libby anti-capitalist.
