The mentality that most people on the vlogging side of YouTube had when the site was just getting started, back before being paid for making videos was a thing and YouTube gatherings were just a bunch of nerds standing in a field. The term was first used by Jazza John (rhymingwithoranges on youtube) in a video he did with Ashley Mardell to describe people who treat their favorite content creators like people, as opposed to objects.
Instead of treating her favorite YouTubers like unattainable celebrities, Amy treated them like they were her friends. She had the 2007 mentality.
