Thing 12 is Rollyo. Now, I have read on other folks blogs different opinions of the tool. For some, the obscure resources they can place in one great useful search tool works for them. For others, the service is trying to personalize a googleesque experience and not as well as google.
I am in that last camp. I rolled my own engine and just do not feel that this tool is for me. I can find most things I need via the Google search logarithm and have been using it for a few years and have learned how it wants information.
So, thought I have a dart supply Library Thing, I don’t see myself using it much. I can however see how someone could use it for their own specialized searching needs.
