Librarian using flux sites?

Yesterday I talked to Deuel School Librarian about Flux sites. I had some extra time yesterday so I went down to the library just to talk to her. She admitted how handy flux sites sound. With flux sites you really only need to be logged in with one of them to be in logged in with all, and generally that site that you have to be logged in with is Facebook. Looks like Mark Zuckerberg's college creation really became useful. It's amazing how one huge social networking site can be connected to all these little ones. When you go to a site and see up in the corner that there is an F or something that says Facebook, that means that it's a Flux or a form of a Flux. Click on it, and it will give you an option to connect with Facebook. I find this to be so useful. I no longer have to remember different screen names, and possibly even different passwords. It's amazing how technology has shaped our world.
