Ask HN: Does the world need another note-keeping app?

i am personally not satisfied with any of the options out there for note keeping. theres plenty of stuff like Evernote and Onenote for writing stuff but I find their one-level-folder organization structure to be hard to navigate and digging up information down the road cumbersome.

i really desire an application that allows me to store all the bits of information i come across and want to save and access later. something more akin to a bookmarking service, but for notes and with search and multi-level-tree folder organizing. despite this being an issue as old as the internet itself and countless attempts to solve the problem, i really don't see or have heard of a solution that does what i want simply and awesomely. this would also be a web-only app so that notes are available immediately between devices and no waiting for syncing.

i want to build this and i want to know if anyone feels the same and if so, would you be willing to pay for a solution?
