This reminds me so much of Maggie Appleton blog post on "Home-Cooked Software and Barefoot Developers" [1]
We have so many people who are so excellent and fast and developing nowadays that we can even afford the time to build things for our community, friends and even just for ourselves.
It has probably always been like this, but I am just personally observing a higher-degree of people doing and talking about it. Even just the small-web/neocities bobble points into this.
I really liked Google Timeline, but started going away from it (in my de-google phase right now), it was nice to go back to when I had been biking a specific place in town, but couldn't remember exactly where.
And I have also been doing some PolarSteps for quite a while, but wanted to start making my own travel books now.
This seems like a perfect tool for both of this!
