I am not a facebook user, and I don't really feel a need to share all the websites I visit with everyone. I don't need a site that is used for data mining to do this. I bookmark things on my favorites list on my computer. That does everything this site does with the exception of sharing it with anyone who wants to look at it. If I find something on another site I want to check out, I write it on the pad of paper that's in the desk drawer in my office.
