I know yammer isn't new #tbt 🙊, but it is a pretty cool product.
Also, side note, posting it helps me fill out my Microsoft M&A Collection 👊- https://www.producthunt.com/@jfi....
@jfilcik@erikclundberg I guess my honest answer is that Yammer came first :). It was the first unicorn of enterprise social (right?). Now Slack is taking off and maybe on track to be even bigger by some estimates. It's interesting how slack emerged at the same time messaging for consumer really took off. Maybe you could say Slack is the first Engineered ground-up for Mobile enterprise social app?
Maybe I'm over-simplifying. Love to hear others opinions.
@erikclundberg Honestly, I don't really use it much with Office on Windows. It's very well integrated with Office Online, posting docs on Yammer lets you edit them in Word/Excel/PowerPoint. I use the iPhone app a ton. It's really top notch.
