http://wallwisher.com/wall/lindas-loop Wallwisher was not too hard. It took me a while at first but it was not hard to use. I like it because you could use it to have book discussions or book reviews. You could post homework assignments or use it to work on story sequencing. You could get very creative with the backdrop. I could use wallwisher by posting notes to my students about homework or having book studies. We could also do story arcs or story sequencing. I would really like to use Twitter to help me with new teaching ideas or to help discover good educational apps for my IPad.
