Yeah, not sure what label we’d give to a system like this but it works. I basically do the same, but with Raindrop (the bookmark manager). I’ve tried many tools and systems, but what works (for me) is basically a personal data lake where semi-structured/incompletely-labeled stuff can be archived.

For todos and calendars, I’ve found less is more to be particularly true. I don’t see how anyone gets solid ROI for non-collaborative personal projects by using feature-filled systems. I’m quite busy, and the minimal cognitive load of pen and paper is difficult to surpass.
