Response to Preface/Ch. 1-2
 Many years ago I had just gotten my first electric typewriter with a two-line memory.  Within a year my husband had purchased a computer with word processing, etc. and immediately the typewriter became obsolete.  In the time of Web 1.0,  I remember using computers in classes simply to play learning games with discs of one sort or another.   In the era of 2.0, I  interact with Facebook, followed my son's blog as he traveled through Asia, and watch my team of teachers use Wikis and podcasts in their classes, I have seen or participated in these interactions first hand.  In Web 2.0 with  the rise of community-oriented technology tools, I understand how computers "fit nicely with the belief that the meaning-making process of learning requires social interaction" (p.6).  This is the area I want to expand in my classroom.  This historic discussion of evolving web use, gives me context to see more clearly where my knowledge base is and isn't, and what I can let go of (like the electric typewriter), and what I need to still keep learning about as we transition to Web 3.0.
