This is a perfect example of "solution looking for a problem". You heard about the thing via Bitcoin channels, you only care about it because it's /Bitcoin/ solving a problem, not because the problem is solved, you can't actually find the thing now!
Normal people, people who haven't bought Bitcoin, don't really care /how/ their problems are solved. This is the fundamental reason Bitcoin hasn't gone mainstream. It doesn't solve any mainstream problems well.
