I find it very funny that all of my nerd friends are all suddenly using an archaic German note-taking system. I started a simple system myself after reading the thread about them here a few weeks ago, and I have to say that it's already been useful. It reduces the lookup times from O(all of the internet) to O(just my notes).
This ^^
I use a combo of Pinboard [1] to save URLs I think I'll want to refer to in future, plus NValt [2] stored on my Jottacloud [3] for recording snppets of info and more free-form notes and for making that info available from any of my devices.
Nine times out of ten [if not 99 out of 100] however, I'll just StartPage or DDG whatever info I'm looking for, since I always have a browser open anyway.
It's also quite common that, having thus found such a nugget of info, I go to add it to my Pinboard or NValt notes for future reference, only to find it was already stored there [often years ago], if only I'd thought to "shop locally" in the first place.
