I've stumbled across that place long ago when looking for an answer to something and I wouldn't necessarily cite them as being the most... objective collection of people. A lot of what I saw felt very emotionally charged, with an emphasis on the charged part. I'd take anything you see there with a generous pinch of salt.
I guess I have a weird outlook on the whole thing, as someone who spent 2 years in a poly relationship, I never felt third wheeled by anything with Lia and Azzy. To me it was exactly what some poly relationships are: your partner has their partner and you aren't always gonna be involved with them and that's okay. As far as I'm aware, mine, with 4 people all dating each other, is kind of rare in poly.
