I'm at a Gartner conference right now (more about that later), but one of the keynotes was by James Burke of Connections (and 2 and 3) fame. I've been a fan for a long time, so it was worth the conference just to see him. He gave just the sort of entertaining and thought-provoking talk you'd expect from him.
Anyway, seeing him reminded me about his Knowledge Web project. He is running it as a sort of grassroots effort, so basically an open source project. As I get a little older and have kids, this is the sort of open source contribution I can get behind because it's easier to see a real contribution to more people (many of them kids).
Now, a question. They have some key technology guys already involved, but they haven't yet selected a technology for their final implementation. Is this a space Perl or some other open source product could inhabit? They need some good interactive graphing, but James made it very clear that they want it to be very polished and fancy to get kids involved.
Any thoughts out there? Are Java and Flash the only way to do this?
