Cycled through many, came back to keeping the old fashioned Google Docs (Word) file. Just have a bookmarked link in the Chrome's toolbar. I envy those who've been using Word file to collect information for many years, well, since the beginning.
At one point, I used a directory of text files synced with Dropbox, vim to edit, and a few bash scripts and vim functions for tagging and searching. It worked well except on mobile.
