Just got back to testing the 'social feed' feature after a couple of weeks and I got confused (which I didn't at first!).
The source of my confusion? The difference (in icons) between the 'social feed banner' and the 'social feed button'

So with the forgetfulness of a 71-year old after a 3 week break, I clicked (in any thread) on the 'banner icon', expecting my 'view' to change into 'social media feed view'. Of course the 'banner icon' led me to somewhere completely different.
So my main tip is to change the 'banner icon' to match the 'button icon'.
My (limited) experience so far is that the 'social media' (nested) feed is a great option for threads that are 'nested' (responses to responses).
