Yet another great tool that almost everyone would find useful. With two part-time jobs plus casual work, I use several different computers most weeks and having access to my favourite or most commonly used websites wherever I am will be great.
Classifying them with tags is very useful, although I quickly learnt to be specific with the tags, otherwise I could end up with countless sites for one classification. eg education or photography.
I can see lots of uses for this in all areas of education, particularly primary, where you want to steer students to a particular group of websites.
