I also use OneNote at work for capturing anything worth remembering in a meeting, and screen grabs from a webex. It captures the text in images and indexes it for searching later, which I do frequently. I don't mix personal notes and tasks into this notebook.

For several years I've used Google Tasks for organizing my personal notes because it's cross platform and works like my brain. I have a small list of things to do today, that rotates frequently, a well-organized larger "Backlog" that I pull from after I've emptied the "Today" list. There are other topical lists like "Music" for notes and tasks that don't usually get flagged as done. Some bookmarks get into Tasks, if I'm pretty sure I'll use them again. But mainly I save stories in Newsblur if I think they're worth revisiting.
