Rollyo seems to be a useful place to organize all of your sites/bookmarks. This could be useful when having students conduct research on given topics. Important classroom time could be used on the actual information itself instead of searching for the info. I had a little trouble exporting my bookmarks to a searchroll, so I did them individually. This worked better for me.For some reason I was unable to view the video created by another player. I will try to view it later, because there were great comments about it.
