I see a lot of comments arguing that it's not "worth it" to spend dozens of hours to "get into org-mode" when there are "intuitive tools" such as Evernote or Trello or Todoist etc. What some are missing is the fact that low barriers to entry sometimes turn into barriers to growth at a later stage. After (!) one has sunk thousands of hours into them. I used to keep my academic notes in Evernote and it turned into hell…
When I visit evernote.com, I see the obvious fails: "sign up", "log in".
You gotta own the data, so that no matter how bad the program turns out to be, you have some a nice local file sitting on your hard drive from which you can ferret it all out somehow.
