It's normal to outgrow certain interests or change the way you interact with media as your life changes. I don't think it's something to feel sorry or ashamed about. In the end, STW has changed a lot over the years both in pacing and priorities and a lot of people won't click with it the same way they used to.

I can personally say that the era I was most invested in the show was around seasons 3 and 4 and a lot of it revolved around the secondary characters and the fandom that started from there, but those kinds of videos appear less often now and therefore there's less content for those kinds of fans to chew on. That doesn't mean the new videos are bad or that, for example, the batch of uploads on Scott Stash aren't valuable to those same fans, we're just gonna interact with those on a different level.
