Connect with vegetarian and vegan friends from all over the world.
If we are targeting non-vegans, we will have to post subjects they are interested in. As there are already a lot of channels addressing animal cruelty, I doubt how much of difference a youtube channel is going to make if we are going to post the same cruelty related videos again. We could stuff cruelty related news/articles with non-vegan recipes( OR anything non-vegans may find interest in). Environmental impact and health issues of meat can also be posted to attract such groups.
