Delicious is a fantastic tool. I think it would be very useful when someone is researching to have access to the other links used by people researching the same topic. The library could really take advantage of this tool - its like someone else doing the work for you, or at least only having to do the work once! On a personal level I think it would be better then using the favorite tab because it is available on whichever PC you are using, not just the one it was set up on. I really think i will use it again after this course!
