Basically, the idea is that there'd be a tab in everybody's profile where you could see all the reviews they left on other people's work. It's an easy way to identify which people just run around being idiots all the time, or if it's someone who's opinion you respect and you see they've left a glowing review on some random story you've never heard of, you'd be more inclined to check it out yourself. And in general it's just another way to encourage people to write more thoughtful reviews, if they know they're easily accessible to anyone at a click.
I'm guess this will probably be rejected, but it was a feature from another writing site I used to be a member of that I always thought would be nice to have here, so figured I'd give it a shot. :)
