Great post John, I liked that you have a written part but you should put some color on it. It would also be better if you have a video on it.

ReplyDeleteNice post John. It looks like you explained the terms well. Next time add a little more color to it and add your video. Other than that, great job.

ReplyDeleteGreat post, John. You explained the terms with great examples. Next time, add your sesame street video and give your post some color. Other than that, good job.
