LinkedIn is just another social network, more work related. When you post something new, you do want to see how many likes/comments. Just like Ins. "Who viewed my profile" is real in LinkedIn. It can be someone who is hiring, someone who may watch your talk, someone who may buy your product. I personally started some business conversations when I realized someone viewed my profile, or at least add they as new connections.

It's part of what makes Pinot so fast. https://engineering.linkedin.com/blog/2019/06/star-tree-index--powering-fast-aggregations-on-pinot https://engineering.linkedin.com/blog/2019/06/star-tree-inde...
