I think she was maybe referring to the topic types that O2L does. Many of the earlier made collabs that I've seen did not really have topics like that. They pretty much just plopped themselves in front of a camera and talked about a topic or their day, without much variety.Just an fyi, it's not like Our 2nd Life, they didn't create collab channels, there have been and are many from before O2L existed.
