Writing too much detail on the landing-page site for my apps is not a good idea, but I wanted somewhere to keep the things I think about while building them, so a blog it is.
That said, I will also post plain notes about whatever comes to mind. Those may well end up being most of it.
I write in English to practice publishing in English. I am not strict about this either: having AI check my writing, or having it translate a Japanese draft, is fine by me.
