As I read and write about the many things that the Internet has to offer, I came across audio for posts. You can make your posts available with audio by using talkr. Talkr is free and has easy instructions on how to make a podcast of your blog.
This is fantastic because there are audio learners who enjoy listening to posts being read. Now, posts can be visual as well as auditory. My students will enjoy making their posts with this audio feature.
