I'd also be surprised.This is the best place for civ discussion online, bar none. Our community is small enough that you can read all the posts each day in an hour. If they don't have someone reading CFC I would be surprised.
But I also don't have a bad experience with Discord (which, admittedly, I'm only really active in the modding channels for when it comes to Civ). I tend to mute all channels that are going to be too distracting; it's more a volume thing than a quality thing for me personally.
It tends to all come down to the moderation. Though I do agree with Oberinspektor Derrick in that the different formats; the different ways communities function can affect people differently. There was a time when forums weren't good for me personally. At another time, IRC wasn't good for me.
