There’s one case where it gets super popular, or attacked by spammers/bots, and the site becomes more effort to operate publicly than you want to do for free.
In another case your girlfriend stops using it, as well as some family, and the continued maintenance over the years feels like it isn’t worth it (because there is always maintenance.)
Either way you might want to shut it down, and promising “forever” to users feels problematic when you’re not being finically incentivised to keep it running. With the financial incentives it’s much easier to pass the burden on to someone else if you can’t run it for whatever reason too.
Piruetas is pirouette, as in what a ice skater might do.
Since then I just gave up on web based tools for notes. I just want to save my notes and be able to recover them when things go wrong. A simple directory with markdown files and hugo blog allows me to do that.
OP how does your app store the journal entries?
