I think this infographic has a lot of important information in it, but the format is hard to read. If the infographic were larger, I think it would be more effective. It would definitely be a good poster to have at a desk, if you’re doing a lot of writing, but you would have to print a larger version for it to be useful in any way.
Besides the size, the information it includes is useful because punctuation can be confusing, especially if you haven’t taken and English class or written a paper in a long time.

I agree that the infographic was tough to read with the color scheme and the size of the font, so it was helpful that the transcript was provided. I never knew the difference between a hypen, en dash, and an em dash. The information was very helpful in clarifying the differences not only in the length of the dashes, but also in the usage of hypens, en dashes, and em dashes. Overall, it was a good refresher on the different uses and cases that each type of punctuation is used in.

I think the information was better explained in the description than in the infographic. An infographic should be quick and easy to read, used at times where someone might not want to read an entire document on the information. Other than that, I found the information on the punctuation super helpful. I like how some of the descriptions explain how the punctuation can be used for story telling such as how the quotation marks can indicate sarcasm.
