MicrosoftThanks for the info and insight. I appreciate where the Yammer team is coming from with regards to these tests and changes, however the guidance "what you see may not be what I see" is woefully lacking in the real world.
It is embarrassing to be the Yammer advocate in my company and not know whether something someone is seeing is a bug or a ... possible new feature. It is embarrassing to have to say "I don't know what you're talking about" when someone asks you about a change they see. Your Yammer advocates and network admins are supposed to be the experts at Yammer and not knowing about these A/B tests only serves to undercut our expertise and status.
The Yammer Community example above is something I'd look at and expect to be a bug. No sidebar? Very disorienting. I'd never have expected that to be a feature.
If the Yammer team insists on continuing this practice it would be extraordinarily helpful for a notice to be sent to Yammer network admins in some way (via the Message Center, or a post in the MTC, or via a Twitter account, etc.). Create a special opt-in mailing list. I don't really care how, but please let us know so that we don't look stupid in front of our colleagues and customers.
