This is actually more interesting of a question than it seems on the surface. I think it's weird when people post on linkedin, and am trying to figure out why. On most social networks, I think there's a surface reason why people are "supposed" to post that makes it not weird. I'm just chatting with friends. I'm engaging with my community. But the emotional reason people post is to influence people to think like they do ("I want people to see me as a thought leader"/"This person is wrong") or to make people see how great you are ("Look at this cute cafe I went to in Paris"). It's a hunt for validation. On linkedin, people post for the same reasons, but it's not hidden behind a supposed surface reason. You post on linkedin to make yourself look like a better person to pay for stuff. It's like how on a resume you really ought to brag, but you shouldn't with friends.
