Using a phone is simpler if all you have on you is your phone, which was my use case when my bank hadn't offloaded their wallet app to gpay. That, and having the phone already in hand for customer/loyalty cards.
So yes, it's handy. Jot handy enough to use gpay for it, of course, but handy nonetheless.
Keep an eye on [Asahi Linux](https://asahilinux.org/), then. A cursory glance shows Me support not being complete yet, but I assume it will be in time (and the missing stuff may or may not be a show stopper for you).
> I really don't understand those artists and writers you mention. Why on earth would they not use their own platform to present their content?
Ease of use. Plenty of folks don't have the skills to set things up and keep them humming along, nor do they have the funds to play someone else to do it for them. So they hand over a bit of control in exchange for a platform that's set up and kept up to date.
You may argue that they're giving up too much control, and I'd agree with you, but that's not how most (non-technical) users see things.
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.
Which, to the general public, doesn't matter one iota.
Luckily, there's other platforms that, apart from giving you more options wrt your database backend, embrace newer PHP practices and versions a whole lot quicker.
So yes, it's handy. Jot handy enough to use gpay for it, of course, but handy nonetheless.
