The lack of decent hand holds probably plays into it's rating.
If you have automatic image resizing turned off then look at
this shot and think of it with no people or cables.
I did find the rock very slick, I got caught in a traffic jam and I couldn't stand in one location without my shoes slowly sliding down.
I'd really love to watch peoples reaction as some hikers walk down way outside of the cables, I went down outside of them but while using the cable and allot of people were freaking out just because of that, Half Dome is definitely a place timid people go, just go and sit with your feet over the cliff and listen to the voices from behind saying your completely crazy lol
