LinkedIn has debuted a sleek new look for desktop, plus new learning portal for its 450 million users.

Looking good

The new layout is more streamlined, and designed to align with LinkedIn's recently updated mobile app.

Profile pictures are centred, while the Message button more prominent. 

Notifications get their own tab, and search for keywords and hashtags has been souped up.

Live and learn

LinkedIn also announced LinkedIn Learning, a learning portal using the content from Lynda.com. And for good measure LinkedIn also launched a bot system designed to help users better manage their time.

And could LinkedIn's engagement problem finally be turning around?

LinkedIn revealed that its mobile app has seen a 30% rise in daily active users, and a 40% increase in engaged feed sessions. Significantly, messages sent have skyrocketed by 240%.
