@simonroses Linkedin provides minimal, but some value…
There are a couple of people I chat with via LinkedIn that for whatever other reason I have not migrated chatting with them over to any other service.
I get some decent job opportunity messages from recruiters there from time to time. Don't think I've ever actually taken/gotten a job which originated from LinkedIn though...
Though most of my (and any one elses) LinkedIn feed is cringey nonsense I do surprisingly find some interesting blog posts from time to time.
I don't have enough analytics on my site to give any useful numbers, but I know LinkedIn drives some amount of traffic to my site, and thus to my other properties across the web 🤷♂️.
It is, in the end, where most jobs/hiring managers will want to turn when they want to look at your “professional profile”, even if you have a blog or w/e else, those will almost always be supplemental to 1. your resume and 2. your LinkedIn profile. So having a presence on Linkedin is important for that reason I suppose. I have taken a somewhat principled stance on how I present myself on LI. Rather than reduce myself to my timeline of jobs, I've decided to instead emphasize my skills, my portfolio (blog), my education, my credentials, and the orgs I am a part of.
