Problem: I have thousands of uncategorized bookmarks. I want to find a bookmarking tool that will let me upload my bookmarks and then automatically tag all of them by category. All the existent solutions seem to at best offer tag suggestions but are unable to organize the bookmarks on their own. Is there any bookmarking tool or hack that can do everything automatically? One would think there's enough data from links and social bookmarking sites and from the website's description, tags and text to do this pretty well.
