Yes, join the cult! Just kidding.
I kind of like the term "Lemons" because the general mood seems to be sour towards reddit from the recent migrants. However, even though lemons are sour, they add a lot of flavor and are a fundamental part of a lot of recipes
I think we're seeing the beginnings of what I call the "Reddit Schism". Once the cats started appearing, it has become official. We are no longer redditors.
Our fruits have become soured, and have soured us, with the latest news from Reddit. Let us, the "lemons" move onto the welcoming arms of the federation!
Aren't lemming, fedizens, and reddit r/efugees referring to different specific groups of people?
It might be best to go with something that has more appeal. That's part of why I went with lemon because it seemed catchy. Lemmings, unfortunately, has historically had a negative meaning. Fedizens is okay, but citizen might be better as it isn't a portmaneau? (new word combined from other words)
