I could care less about any host's lives. I've never read a blog nor intend to. If one is not there sometimes, I'm usually happy. They're about as worthy of interest as a clerk or salesman in stores with a door.
I would be very happy if they did not waste 15 minutes to a half hour on one item and showed us more so there wouldn't be time for that.
There IS one thing I enjoy about hosts and vendors and that is when they show their pets on air. I don't buy Susan Graver, but I watch for Pebbles all the time.
I have an interest in seeing their pets, but not hosts.
