So I have tried to avoid all those cool little links at the bottom of stories that say dig.it and what not but I figured that I might look into them a little more and so I clicked randomly on a show me more button. Below looks like a good starting place, a list which it would seem encompasses at least the linking and sharing aspect of all this. In my idle hours, I will try to find more and make sense of all this stuff. For example, I am on LinkedIn and have heard of Twitter and Facebook, but what here is really helpful and can make what I do, better.
