I’ve been using del.icio.us to store my bookmarks lately. If you haven’t seen it yet, del.icio.us is a social bookmark application. You can add your bookmarks to the site and store them under specific keywords. You can then easily browse your stored links by the topics you have added.
Where it gets extra-nifty is that you can also see what other users have been posting under the same keywords. Each keyword provides an RSS feed of new entries, so you end up with nice feed on a particular topic. For example, here is the feed for KM. You can even subscribe to an RSS feed for all the links posted by a particular person. Here is my del.icio.us feed.
Del.icio.us also provides web service access to its data, so you end up with tools like Foxylicious, which is a wonderful extension for the Firefox browser that imports all of your del.icio.us entries into your Firefox bookmarks. Excellent.
