I really miss a professional newsfeed in teams.
I know we can create a newsfeed from the sharepoint teamsite. But it aint really fitting into Teams that good.
A newsfeed should have options of showing several news in a more compact manner. Also, news need to have an enddate so only those that are relevant are showing for your employees.
The chat/conversation is not replacing the need of a newsfeed since it is not very compact and it is hard to get a quick overview if you have anything new to read. Specially in teams where all members are able to type.
