Not an easy question to answer. I think if I were to sum it up, most of us were bored. I think when we started watching, we were drawn to your personality. Your choice of words and phases were different than the norm, along with you were a bit quirky. I think we related to you and found humor in what you were offering. I suspect Scott Adams nailed it so well because so much of what he provided, many of us could see in our own lives.
So what's actually changed (or hasn't changed) that has made it more "boring"?
I don't think any of our small group watched for the technical content so much as just watching you entertain us.
That is not uncommon for my audience. I suspect it's the majority actually, that they watch for the entertainment value essentially.
Around Christmas as you started to talk more an more about religion, I really lost interest. I have no care of what your views are but found it a little sad to see you begin to attack a group a people based on religion. I remember saying, it's his show not ours.
See my comment above, I have not done a single video on religion.
Mailbag is called Mailbag for a reason. Name another video I have mentioned religion (apart from a 2nd channel video on Peter Poppoff)
But hey, if you want to lose interest over that then I understand, perfectly normal. A couple of orders of magnitude more people lose interest over other things I say and do. My comments on religion would be down in the noise for reasons people unsub or don't watch any more.
