How we communicate with others matters. In fact, it matters a lot. Even today, when VIDEOs are wildly popular, it's not always the best way to get your message to others. Writing is VERY powerful, but communicating in writing has its pitfalls. When you communicate in writing, you cannot convey all the information you might normally get across by speaking face to face, because your reader cannot see the person's face. They cannot get clues about your attitude towards them, and you can't get clues as to whether or not they understand what you are trying to say. 

On the flip side, one barrier to persuading others is your age. Many grown ups will look at you and think, "You are just a kid. What do you know?" But in writing you can level the playing field. If you present yourself well using an accepted format, you can often get others to see your point, and win them over.

     Designer and blogger Jennifer Farley published this article "GIF, PNG, JPG. Which One To Use?" that also does a great job of explaining the differences between the popular web formats, and with examples to demonstrate visually the quality (and transparency) as well as the file size.
