At the Network Updates there are: Status Updates, Group Updates, Recommendations, Questions & Answers, Job Posts and Connection Updates. My advice is if LinkedIn leave those options closed, and just put as a title as I did before, it would be much better. If the user wants to see more, they would just click on the title and all the information would appear. The same applies to the Group Updates too, as it is better to leave just the titles on, but closed, and if there is the curiosity to open them, one click would be enough.
According to my point of view, there is too much unnecessary information placed twice on those updates: Instead place it by time: last week and 2 weeks ago, why not to put by the number of the last 5, 10 or 20 operations? I am proposing it because at the same time that LinkedIn have some very active users, another group of users may have just few activities, for this reason, a time frame reference may not be ideal in this case, but by the number of the last operations.
