This is turning into a "thing" on Techi. The good folks over at AnonymousFO put out these great compilation videos of UFO activity from around the world. What is making this possible?

1. More cameras available in our pockets at all times thanks to smartphones
2. Greater connectivity and a broader audience thanks to YouTube
3. A dramatic increase in UFO activity across the globe
4. All of the above

We think it's #4. What are your thoughts?
