I'll be honest here, I haven't looked into this at any depth, but it sure looks cool at first glance. Build an online scrapbook complete with pictures (and all sorts of visual effects), hyperlinks, text, and more. Then you can share it out to others when you're done.
The problem that Education always has with this stuff is that there are often folks who like to make trashy scrapbooks. I didn't find any, but that's not to say that there aren't some. Wouldn't it be great if sites like this insisted on folks keeping it clean? Or, like TeacherTube, make a separate site that is Education friendly.
Think about this. Google is sitting on $12 BILLION in cash. What do you do with that kind of money? You BUY stuff. They COULD be buying stuff with the idea of making it kid safe and Education firendly.
Maybe in the perfect world, eh?
Let me know what you think about this site.
