The last few years have re-arranged my expectations. If you had told me an instant messaging platform like What's App would get acquired for billions I would have laughed. ICQ, AOL Messenger MSN Messenger, etc. had already come and gone. If you had told me one of the hottest IPOs in 2017 would be based on a photo-sharing app, one that doesn't even persist photos for very log, I would have laughed. If someone had sat me down in 2007 and said Flickr would be overshadowed by SnapChat I don't think I would have believed it.
