That's a good observation. LinkedIn is so boring and chill, you can actually have difficult debates on there with everyone being polite and accepting lol
What's strange is facebook. The fact it's more segregated by close circle make the discussion nastier than on linkedin when you have your company name on top of your mean troll.
Take the name for example. Any other platform has a clear written or unwritten rule.
- HN: usernames
- LinkedIn: real names
- Twitter: a mix
On Twitter, you clearly lose out if you put your real name out there. You suddenly get trolled by strange avatars hiding their identity and very little community control.
