This is likely why LinkedIn is so non-focused on one workflow. Everyone wants something different.
In my case, I don't want to hear anything about what people are up to. I don't want articles, or other such stuff. I don't want to be messaged.
For me, I just want a work history validation mechanism, and a way for legit job offers to appear.
The perfect linkedin for me, would be a way to link to work contacts without ever talking to them. Once linked (eg, when people allow it), I could get contact info if a person has it setup. That is, an email address or similar.
Again, the platform would have zero communication on it, so if you want to talk, then take that email, and email the person!
Outside of that, I want nothing. No communication, news, etc.
