No idea what they were smoking when they decided that their target customer was Snapchat users. Skype is still relevant to me in 2018 because their core streaming tech is in my experience still more stable/reliable than Hangouts/FaceTime/Slack etc. Often Skype still connects on a crappy network when these other apps fail. This alone has made it my go-to for mission critical video chats. All I could do was cringe in embarrassment when trying to schedule business meetings and seeing those squiggles pop up all over the place.
Skype UX doesn’t need to be “fun”. It just needs to be usable. Kudos to the powers that be for making a tough call to benefit their core userbase.
