The Skype you know and love has a fresh design and a ton of new features to stay connected with the people you care about the most.
I understand that mobile has to be the priority for any platform, and that naturally means competing with iMessage, WhatsApp, Messenger, Snapchat, etc. But, anecdotally I think most people use Skype differently than those platforms.
Skype is closer to LinkedIn than Snapchat, and this redesign makes it feel like a me too app, rather than stand up on it strengths. This makes it more likely that you’ll start using the other — more popular — apps for what you use Skype, than the other way around.
My bet would have been to a friendlier Slack type solution, that takes advantage of pre-paid credits rather than paid plans for advanced features.
