Don’t get me wrong, occasionally using cloud products is fine. But if I’m going to dump my brain into something and depend on it throughout the day, I want to either (a) have complete control over it, or (b) have an easy exit plan that allows me to migrate to something else with minimal effort. Oh, and I guess (c) it should work without an Internet connection.
Yep, fully agree: siloing, poor offline support – also reasons I’m avoiding proprietary products as much as I can. Personally I’m a heavy org-mode user :)
For taking notes I’ve started using the “desktop wiki” zim and found it to be good enough.
