Just like what we are doing right now, every one is naturally engaged, expressive to their opinions, support others when they ask questions, and the normal communication. LinkedIn on the other hand, is the opposite, one way communication, so much overly positive feedback that it sounds like bots, and if you question or provide a constructive feedback it will be seen as a negative one, and most people aren’t naturally engaging because they are afraid of any consequences like being fired or similar.

got it. Should it be anonymous or transparent?

I don’t think you can have anonymity on LinkedIn to be honest since your employer or your company is there, but maybe more of a website userbase culture shift on how to engage, which is not easy, HN for example have their own way which is ok for the most part, other sites are also different where you might have some pseudo anonymity, others with no likes or upvotes.
