Textbooks vs. PR Books

In Social Media class we are reading books that are very much unlike textbooks.  I find that in all of my other classes I read a highly overpriced textbook filled with lots of words whose meanings sometimes get lost in my head and the concepts are hardly ever explained well.  With the books we are reading in Social Media I am interested in the topics.  I hardly ever find myself drifting off of the subject and becoming bored while I read.  The concepts are very easy to apply to real life as well because they give concrete examples that anyone can understand.  I think that I learn more in this class because of how interesting the content and reading are to me.  (Maybe I'm bias because I love social media) But I really wish that other classes could find a way to make the information more exciting and keep the students interested in what was going on in the class.  I realize not all subject are easy to make exciting.  Like for instance my accounting class.  But if we were reading more books like this than our horrid textbook maybe I wouldn't find myself daydreaming as much as I do these days!
