I worked with http://del.icio.us and at first, was frustrated because the fields to fill in seemed different than what we discussed with Karl. After I spent a little time playing with it, I am thrilled about it. I find sites at home and can come to school and there they are! I am loving the tags, so you can look under certain labels to find some or many links depending on the category. I was glad I "took 5" on this, even though it took many "take 5's."
