A little over two years ago, Olivia Biermann started posting videos on YouTube about how to make healthy, inexpensive vegan recipes. She slogged away, making those weekly videos for about eight months, for a relatively small audience of faithful viewers. Then, something happened that could only happen in this era of social media. One of her videos went viral, garnering over 90,000 views within a few days. The rest, as they say, is history. Although that story is still being written.
