Full-text search over the pages you've bookmarked. For me, the Firefox address bar (with its rapid search of your browser cache) has made sites like Delicious obsolete. The only webapp I'm aware of that lets you do this is Google Bookmarks (which is asocial). I'm still waiting for someone to bring the pleasure of the Firefox address bar to a social site. I created a webapp that does this last summer (Quocial.com; I can send you an invite if you like, but be warned that I'm no longer maintaining the site), but the technical difficulties of full-text search are such that it really only makes sense for someone like Google or Microsoft/Yahoo to do this. Or, Twitter could start crawling links and letting you run full-text search over either your links or those of the folks you're following (though I'd rather not make each and every one of my links public). In short, the social bookmarking game isn't over yet. I firmly believe that Delicious-style tagging will give way to full-text search. One of these days, someone's going to nail it.
