The majority use LinkedIn only for job searching and keeping contacts.
I do some times wonder if any hiring managers see a lot of LinkedIn social post activity as a positive thing. The few times we’ve interviewed candidates who had a lot of LinkedIn posting activity it was considered a risk: We could go through their LinkedIn activity and see that they must have been spending hours posturing on LinkedIn and replying to people everyday during the work day, which looks like a big distraction when they’re doing it constantly.
