In the land of technology, there rises a great app, THE app. The one to end all apps. The app of apps. It's titled "Blink". DUN DUN DUN. So now the title is out of the way, we can go into what the app is about. Basically it is a messaging app (original!) that allows users to share messages that after a while self-destruct. So basically the message just disappears possibly in some dramatic way. Don't worry, the phone doesn't actually self destruct. It's no Mission Impossible scene here.
Now, as well, it's been taken over by Yahoo. It could very well be similar to Snapchat where you only get to see the messages for a limited amount of time and then it disappears.
Here's a quote from Blink:
"We built Blink because we believe everyone should be free to show the
same honesty and spontaneity in their online conversations as they can in person."
I'm sorry? I think you find we don't just suddenly say something to someone and then self destruct in person because that would be pretty strange.
