I downloaded it today. Cute idea. But it's got a long way to go. Blocking a user doesn't seem to work. Crashed 5 times in 15 minutes. Doesn't seem to be a way to filter who you listen to. So if a user posts 10 things in a row, you have to keep swiping to get past them. At this stage, I only imagine people would use it for a few minutes when they are bored.
