So in my current novel, a couple of college students catch the witch doing something extremely, visually magical on camera, and it gets posted on YouTube. The exposure of magic in a world where some very powerful, vindictive people want to keep magic all hush-hush was going to be a major plot point, until I thought about it.
In real life, half of the comments on that post would be “FAKE!!!1!!” and other videos would pop up mocking or breaking down the special effects of the original video. And then there will be the memes. So basically, the reality of the Internet killed this storyline for me.
