I love LinkedIn because it helps me stay in touch with people who I went to school with and old co-workers as I deleted my Facebook account years ago. If I didn't have LinkedIn, it would have been much harder to stay in touch with those people.
I do think that LinkedIn has a lot of low quality content so I entirely avoid the feed and use it more so as a rolodex and that alone makes it worth it for me.
