It's owned by Automattic, isn't it? I assume they're simply keeping the lights on for whoever wants to use it.

For about a year I've noticed that it tends to quit on its own on my Mac. Whenever I need to look for a note I realize the app is inactive and I need to re-launch it. Then it works perfectly well, until somehow, at some point, it quits without me realizing.

It's sad that they're not fixing it, and that eventually it probably won't work with newer Mac OS and iOS versions. I should start looking for a way to migrate off of it.
