@Dennis732. Hi Dennis, fair questions. As a host who doesnt have time (yet) for leisure travel I happily jump between sections (I consider the other four guest inclusive) and addressing both guest and host questions where I think I can add something. Once I am a guest I expect to continue this. We only get one profile so I'm not suprised Airbnb programming hasn't altered this, though it would be nice 🙂
The Host Circle as a host only zone does provide essential feedback to both hosts and Airbnb on important issues that may be confidential in nature. If this was open to Guests it would also get rather cluttered imo.
As to latest layout its even less relevant to the average guest than the cool listings, again imo.
