I've been on LinkedIn for about 12 years now and I'm on the verge of deleting my account. I found my latest job through a LinkedIn ad/recruiter, so it has that going for it. However, it's generally a chore for me to sign on and check on things. From my experience, the posts on my home page are about 60% humble-bragging, 20% legitimate professional updates, 10% recruitment/advertisements, and 10% actually helpful info. It's basically Facebook in professional attire. In my mind, any platform driven by algorithms is counter-productive (and yes, I realize that's a lot of the internet). In a nut shell, I have yet to see much value in LinkedIn beyond a basic job-search tool.
If you want a professional presence online without losing your sanity or faith in humanity, I recommend creating an e-portfolio website (e.g. Wix). You can link to it on your LinkedIn page if you want. It's a great way to keep a detailed record of your job experience, especially if you're in a research or design field. When I've been neck-deep in modeling, I've found value in Stack Exchange or similar websites. Unless I'm mistaken, these forums tend to address what the LinkedIn Groups address(ed), though I have not dabbled in the latter.
I apologize if I'm stomping on anyone's birthday cake with this negative review of LinkedIn. If it works for you, great! I don't waste my time with it if I can help it.
