The very first thing that you'll notice whenever the new LinkedIn homepage rolls out to you is that it finally looks like a social network. Gone is the text-heavy stream of updates, having been replaced by a media-rich feed that if anything, looks a little bit like Google+.
The whole thing is different, but the big change is the update stream, which is cleaner and a bit heavier on the media - especially photos. Boxes such as "People you may know," "Who viewed your profile," and "Jobs you may be interested in" are still there, and they still reside on the right-hand side of the page.
The stream has also been augmented to throw important updates to the top. "Important updates" constitute things like "trending topics, news, and professional updates based on what your connections and industry are reading, sharing, and discussing."
Also, the news feed now has infinite scroll and displays all comments and likes out in the open as well:
We’ve completely refreshed the way updates look and feel in the stream with richer visuals for easier scanning and viewing. You can also see a continuous stream of updates without clicking “see more” to access all the latest updates from your network. It’s also easier for you to see what your connections are talking about and engage in these professional conversations by liking, commenting or sharing the updates that are most important to you.
I've yet to see the new and improved LinkenIn homepage on my account, but thankfully LinkedIn has given us this screencap of what everyone will be greeted with eventually. They say everyone will have the new homepage within the next few weeks.
