I really like this app!! I plan to use this in my classroom for book blogs. Each one of my students will create a blog and link it to my blog. There we will blog each week about the book we are reading. The students will have requirements that they have to meet for their blog. Then, each students will be responsible for commenting on their classmates blogs adding their own opinion about the book blog. The students will be interacting and collaborating with each other on the different books they are reading.
I can also create a page where the Blog rubric and informational page is posted so students can look at them for reference. Also, I like how I can only share it with people I want to share it with.
