Social Bookmarking

Social Bookmarking? I guess I see how you could use it in everyday life but I am not sure about my classroom. I think if I visited sites each day this would be helpful but at this point in my teaching I do not check sites each day. If I need a new idea or want to read about others lessons plans I would use websites. Then social bookmarking would be helpful. I have so many sources now that I am not use to going to the internet for information. This is the first year I have internet in my classroom that and I need to get use to using it more.
