I already miss the Yammer network. Much better for keeping up

I am finding the new community set up to be depressing. Where's the app so that we can keep up on the go? And the mention of this being a "new community" doesn't acknowledge the fact that there was a community of over 80,000 people. It was awesome. I get the sense our old community was just killed. Did the content move over. How can you kill four years of community input and guidance? In my opinion we should be building upon the original network, not starting over. Our school would never have made it as far as we did with Office 365 had my team and I not been able to contact such skilled people so effortlessly in Yammer. Now it feels like were just left to start over again.
