More on social bookmarking. This seems to be very much something that is a great resource for teachers. The bookmarking process is wonderful for teachers to share bookmarks. I like that it is easy to share links if you know someone else’s user name. The ability to tag and search for those same tags elsewhere on delicious provides some serendipity.
Again, I see this as much more useful for teachers and professional sharing and development. For those purposes, it is quite useful.
