All the things this program claims to solve are problems it created by being something other than just an actual notepad application running on your local computer.
I think you suggest a point, though, that it seems that it would be ideal to have a general secure and accessible file storage implementation, with specific apps where needed.
And personally, along the lines of what you're saying, I'm actually more concerned about finding a really good, local note-taking method than even involving the cloud or de-centralized Internet in some way.

But if you want to access your notes on different devices (mobile phones for example), that's where something like YourNote comes handy.
