Thing 12. Do You Digg?

I have always wondered what the point of these tools was and, to be honest I am still wondering. This seems to be a huge productivity detractor to me. I do not know why I would want to go to another site to read articles just to find out what other people have to say about it when most of these same websites have comments sections on their pages. It just seems like an extra step that doesn’t really get me where useful.
