Meh. A lot of us nerds on HN spent our youths in chatrooms and forums. This isn't very different. In fact, I would have loved to be able to play with face filters when I was a kid. This isn't a Las Vegas-esque game that costs money, this is communication with friends and family. It's addictive, yes, but it's addictive for the same reason talking to other people is addictive, because it's fun and it stimulates the lower rungs of our maslowian pyramid.
