Ivan54 Thx for the feedback, Ivan. I'll tackle a few of your Qs that remain in this one reply...
- We're getting good feedback about communication sites already, one being consistent about a mehtod to rollup numerous comm sites, and that would compliment the pattern we are establishing: page > collection of pages (communication site) > collection of communicaiton sites (broader comm portal (for lack of name) > ??? and beyond :-). We'll have more to say at Ignite as we refine comm sites, the underpinning pages, news, web parts ... and turn attention to the next level up and how to present a collection of a collection in a mindful way and at the right level ...
- We hear you about the root site. It's one we usually don't touch, but make sense with some of the new modern tech to review it. If you've not enabled any publsihign features, you could certainly create modern pages there and deem one your home page if you weanted.
- Events web part answered by John_Sanders :-).
- News comments are not Yammer powered, but unique tech we have so we could have per item comments - so stored in the same site collection and mapped to the pages it's located on.
- Good feedback on SP home - I'll pass it along to help promote all my stuff, not just stuff I'm active in; good feedback.
- Communication sites are not linked to one group like team sites, and you can permission a comm site with numerous group AAD objects. The site owner defines how broad to go - might be tailored to a few groups, or at company level if you were to use "Everyone except external users" as a broad-reach scenario.
