Mark Oehlert asks, "why do we really have no visible drive in this space to scramble after those dollars with new and exciting products and cutting-edge implementations of new technology that you can try for free for 30 days or for life but at some point you'll pay for the premium features?" Because the education web isn't like that. All this screaming web 2.0 hype is hyperbole, and we all know it. It's not a good thing. We have our innovation in the education space - look at the work around the Personal Learning Environment - but it's open source, not some commercial app with a business plan directed toward IPOs, buyouts, and lawsuits. Well, not most of us, anyways. P.S. mark, not to be snarky, but a few of us non-commercial people know a thing or two about informal learning too.
