After peeking at that BP My Home Plugin - wouldn't your use case also be covered by Nextcloud with a sprinkling of apps? There's a very capable RSS reader available, notes apps, calendar with CalDAV support, address book with CarDAV support, and so on. Depending on what you're actually trying to set up, that might work better than trying to shoehorn functionality into a blogging platform.

I've been meaning to spin up some nextcloud and experiment with the options. It does sound like it's very close to many things I've been wanting to put together as an option for family, friends, and whoever to spin up their own watercooler making a facebook replacement.

Having some experience with BP, it's really easy to get running, and even easier for other people to create a profile and start using it. Is there options with nextcloud for family and friends to join in any of the modules and have their own slice within it?

I'd love an easy button for people to get hosting and spin up a well defaulted nextcould, or buddypress system, or anything similar. With a BP setup, only one person in a family would need to spin up a server and everyone else could use it.. backing up data is the current weakness for easy button with that system, but I see that changing soon.
