My guess is she trained the guests less familiar with Reddit on how to have a successful AMA (e.g., “don’t be Woody Harrelson”).

And because they were so successful, publicists were probably more willing to allow them to happen.

Same. I loved AMA back when it was new and was a mixture of famous people, interesting jobs, or just people with unusual stories. Victoria did a good job of balancing those and making the ones with famous people still feel fairly authentic.

After she was fired, AMA became almost entirely famous people shilling stuff like a generic forgettable late night interview show. I unsubscribed.
