Edmodo user interface was recently updated and my initial impression is that the home screen looks more like Facebook than ever before. The new home screen puts a feed of your students' activity in the right hand column, puts links to all of your courses in the left hand column, and puts tabs to access and manage courses at the top of your center column. This is just like what I see when I log in to manage my Facebook page for Free Technology for Teachers.
Edmodo's new insights tab lets you quickly see how your students are reacting to the content that you post for them. You can also use the insights tab to post feedback to your students.
