I hadn’t really thought that much about web 2.0 really means but I like a recent definition I found:
web 1.0 – one-way communication – the website giving ME information.
web 2.0 – two-way communication – facebook and twitter and the rest – people using the web to communicate both ways
web 3.0 – collaborative work via the internet – MANY people working together at the same time (maybe like Google Wave?) or accessing semantic information using intelligent filtering and searching..

The same sort of definition could be applied to education I suppose… see what you think in Steve Wheeler‘s Blog post at http://steve-wheeler.blogspot.com/2009/04/learning-30.html
