Agreed. It really does not mean anything. I stay at many airbnb's throughout the year and the 'super host' status has nothing to do with the experience. Reviews are all that matters.
I just lost my superhost status at my airbnb. Simply because I fell behind on the response rate. Everything else was perfect. This was for a reason and I wouldnt change it if I could. Someone with no reviews kept asking odd questions so I moved on to the next person. I also may have two conversations at the same booking time and I hold off on getting back to one of them, always because that person has no reviews, and it hurts my response rate. I just ignore the superhost thing and do what is best for me.
