From Anything 2.0 it is sure that the 2.0 has been used for diverse ideas. The main purpose of using 2.0 as a suffix has been to show participation between web administrators and the readers of the website. Just as the .com also had its effect in having some businesses adding .com to their business names, the “e” for electronic also had its own time. I think the ‘e’ formerly ‘e-‘ started with email and then we have elearning, ecommerce, ebusiness, escience etc. This show how einnovative (e-innovative) or innovative 2.0 we can be, to show our presence in the “new thing”.
The addition of prefixes, or suffixes to terms are forms of participation. These additions to “anything” are like comments from the public (critics). In the form of interviews or lectures, some of the inventors (creators) of these prefixes and suffixes have responded to the critics, and also the general public (spectators). The concept of Long Tail also has its effect on Anything 2.0 because as time goes by, new words keep coming up and joining the “Anything 2.0”
In chapter 5 of Library 2.0: a guide to participatory library service, Casey and Savastinuk gave two elements that make a service Library 2.0 as 1) constant change and 2) participation. Though technology was not included, but they mentioned that “technology is the tool that the administration employs to help them and their customers carry on a dialogue in the easiest manner possible.” I would include Technology 2.0 (Web 2.0) as a necessary element. So, my litmus test for services that are Anything 2.0 would include constant change, participation, and technology 2.0.
