Senior software engineer Laukik Watve wrote in the LinkedIn Blog:
Our member profile has been completely redesigned to make it easier than ever for users to connect and communicate with their professional network. In addition to the layout changes, we’ve also added several new sections to the profile, such as recommendations.
A great way to build your own network is by viewing other people’s connections, and now you can easily view the connections right from the profile screen. Even better, we’ve added access to our popular “In Common” feature. Now if you are about to meet someone new, you can quickly find out who you know in common with that person with just a single click.
We have made it easier to view detailed profile updates in your Network updates. From a profile update, you can now tap on your connection’s name to go to the top of their profile, or tap on any section to jump right to that section.
