You may have noticed that the LinkedIn experience is different on the laptop and mobile. A handy feature on the desktop version is the ability to quickly zero in on useful content written by people within and outside your network.
On the home screen (far left beneath your mini-profile), is a section named 'Your Communities'. Here you can add topics of interest, pinning favourites and adding others.
For example, I have #pr #publicrelations #mediarelations #corporatecommunications #cybersecurity #artificialintelligence #socialmedia
Then just click any one, and your home page will be filled with posts with the hashtag you clicked on. Useful to read, like and share.
Adding hashtags also broadens the reach of your posts and is a good way in which to alert people outside your network of interesting content.
