For myself, I tend to use OneNote. Not because I'm an MS fanboy, but because it allows me to keybind WinKey+S to capture one section of the screen and sends it to the clipboard. Most of the time I'm attending webinars with lengthy powerpoints, so doing that lets me pull the salient information out and type out relevant notes next to my partial screenshots. Then it's just subdividing into tabs and subtabs.
