Storybird and Smilebox

I really liked learning about storybird and smilebox. I can see how both would be very useful in the classroom in their own ways. Smilebox would be good for things like class scrapbooks and slide shows, and storybird would be good for younger students. In a high school history classroom though, these two websites may not be that useful. They both seem like they would be better fit for a younger classroom, although smilebox maybe useful for a slideshow, or something of that nature if powerpoint wasn't available.
