Where are we on the (educational) hype cycle?

I liked this cool looking graph from Techcrunch today, not just for its look at technology (I agree that tablet pcs are probably about to get some real impetus in the next year or so) but also because of its illustration of that cycle of innovation, expectation, hope, disappointment, small movements forward.

How might we apply it to educational technologies: blogs, wikis, IWBs, twitter, LMS systems? Or how might we apply it to educational ‘reforms’ or ‘revolutions’? Where does statewide testing, league tables, peformance based pay or the debate between phonics and whole-language sit on this continuum?
