It seems like at all of our gigs people are taking pictures/videos of us with their phones. I have no idea what happens to it after that. What/how/where can I get people in the audience to share their photos/videos with us? Although we have a Facebook page, this does not seem to be working. Do we need to go to Instagram, Snapchat, Twitter, some other thing I don't even know about, etc.? Thanks for any advice!
