Thing 8:Social Bookmarking and Tagging

I went through Thing 8 at least twice so I would understand it correctly. I'm not sure I will use the Diggolet since I share most things on my social websites of Facebook & Twitter. Its a great too if your job has you working with the internet alot and you need to have many sites at the ready to look at, but I thing simple bookmarking is enough there isnt enough time in the day to venture off into Diggoland.
