For my project I want to be diverse in what kinds of media I use if anything for the sake of variety. I want it to be dynamic to keep things interesting. But at the same time I don't want to drown the reader in pictures and videos and audio. They have to be supplementary.
Definitely going to have some video. A documentary-style intro (probably) with screen caps and a voice over. Very brief. Little snippets.
I also want animated gifs. I want to be able to show something like, for instance, someone "Liking" a person's post. It's better than a picture because it actually shows how it's done but you don't have to replay it over and over like a video. It will just be a looping moving image. Being that I want to show certain things like liking and reflagging that do no take long to do, I don't think each instance has to be a full-on video. I'm rambling but I know what I mean. I just have to explain it better.
