I've used Yammer since it was first tested out within our firm more than a decade ago, and have been a community manager ever since. As a result, I've always used the All feed, which gives me a chronological view of all posts made to our network.
We just got access to the New Yammer preview, and unless I and a large number of my colleagues are missing something, there's no actual All/chronological feed, and there's only the algorithm/machine learning recommended feed, or a feed of the communities you follow.
This makes using Yammer just about useless, and makes me much less interested in using the site if I can't get a feed of all posts made from oldest-to-newest. Please someone tell me I'm not the only one that uses Yammer this way, and someone assure me there's an effort underway to restore a proper All feed.
