Web 2.0 means being able to do more things with
applications that are readily available and in many cases free downloads. The example of teachers checking on what everyone is doing in their classroom and trying to integrate similar content in their plans is a possibility, but i don't think it is here yet. It shows the
possibilities though and how much stronger the curriculum could be. With all of the information and topics that are out there today it is impossible to know everything about a particular topic. It is important to collaborate with colleagues and anyone else with similar interests in order to retrieve information. Web 2.0 allows instant feedback to anyone wanting it.
Personally this means being able to contact anyone no matter where they live and talk or/and see them live. Information can be retrieved to help solve any problems such as how to do or fix something.
There is so much information out there the biggest problem is trying to sift through it all and separate the good from the bad.
