Tabs navigation is much, much faster in Yammer now.

Yammer is or tries to be the Facebook of enterprises. The company has been acquired by Microsoft a few years ago and it seems the team has kept its independence within the company. However, I'm not sure Yammer is the goto platform when it comes to collaboration within the enterprise. Microsoft, obviously, uses Yammer internally. They updated it with some serious performance improvements, to the point of stating that the "Loading icon is an endangered symbol". In other words, navigating through the Groups, Feed, Inbox and Notifications tabs will be "much, much faster now."
