Can you post the video link if in case that will push through. Also, aside from millennials, you need to consider also individuals whose age ranges from 20-40 as they are still very active in social media also. But you need to think of outstanding feature that will catch their attention.
Millennials part is just the beginning. We need to create a virality so others can catch on and what's the best way to do it? Well through colleges and youth who are the most active around social networks and who wants to try new things, they are well connected and they have a lot of friends around them and once their friends start using it, of course they will use it because it makes it more fun and engaging.
I'm sorry, what video link?
