The Safari bug was announced. I like the idea, but I wish there was a method of letting users index featured sites (tagging or the like) to help people find related sites.
I'm a fan of certain kinds of sites. I'm a sucker for elegant interfaces and elegant bookmarklets, for two things. And I think that some sort of a way of identifying those sorts of sites would keep your layout elegant, while at the same time letting people into particular sorts of sites find good solutions.
