I use Pocket to grab interesting content as it swooshes by. :-). If it's worth keeping, I send it to Google Keep, then use Keep's color codes to organize material by rough use cases (code, product management, hobbies, behavior, ...)

I then periodically clump similar content into a single Keep note, usually by simply cut/pasting the relevant links. This happens once every 3-4 weeks.

Now if only Google's Keep team would publish an API...
