Along the same lines as Digg and the new Netscape, linkcritics (Quality News, one link at a time) is a site where readers submit, discuss, and rate links.  It's a really new site, so there isn't much content yet.  But the links currently on the site are interesting and unique.  One benefit of its current lack of hugeness is that readers don't have to sift through 200 articles a day like on Digg.  The site also claims to not be plagued by rigging problems (like the whole User/Submitter fiasco).  The site's powered by Pligg, the open-source package for making Digg clones.
