Is there a way to balance the needs of quick access and comprehensive indexing? I think the answer is to have two types of bookmarking solutions: easy access and long term storage. Let’s look at a real world system that helps illustrate this point. Bookmarks can be used like a standard filing system, whether your files are paper-based or electronic. Filing systems are usually divided into two types of storage: short term and long term. Short term storage is used to house the information that you need at your fingertips, like current project files, phone directories, contact lists, and so on. Any files that need to be used hourly, daily, or weekly belong in short term storage and should be close to you for easy access. This information is very important for you to do your work, but it might have limited value for anyone else. Long term storage, which is sometimes kept in a different filing cabinet, different room, or different building, is designed for the documents that you need to store for months, years, or even permanently. A robust tagging or indexing system can be used to keep track of this kind of information that must be kept, but won’t be used very often. Now back to the Web. The paper filing systems analogy applies nicely to bookmarking systems. Social bookmarking, however, is not only good for long term storage, it’s also designed to share useful bookmarks with other people.
