Interesting. I absolutely would horrify people. Especially children. Like ruining their sleep. Mess with them until they are admitted to the funny farm. Grow a habit out of that and do that over and over again, in different areas of the world until I become a legend of a nightmare that actually comes true.
Our public library has the function to borrow e-books (called onleihe, but this counts only for some libraries in germany). I use this a lot.
I think it is, especially when the default doesn’t communicate well with a different ecosystem (Android vs iOS). So installing a app that gives you more features than plain text and works with all relevant mobile os worlds absolutely makes sense.
Does porridge or overnight oats with fruits count?
