For those unfamiliar: these are awesome, but pretty basic, features of Org. In addition to a plain-text syntax for outlining and making lists (for tasks or otherwise), Org syntax offers:

- tags

- properties (key/value pairs that can affect things like export behavior, but also have their own API)

- dates, timestamps, ranges of these, and repeating dates/timestamps, as well as more complicated complicated scheduling via integration with Emacs diary (e.g., a class that meets every Monday from January until May)

- per-file configuration variables (e.g., configure your TODO workflow in a given file to be: TODO -> INPROGRESS -> WAITING -> DONE)

- priority of TODO items

- hyperlinks to local documents, URLs, emails, address book entries, etc.

and more. I'm just listing the syntax I use. And this is to say nothing of Org's many great features beyond its syntax, like the capture interface, the publishing framework, and the many useful exporters.

Not bad. That's how I keep my todo lists, after having quit Basecamp:

  IDEAS
    One Idea
    And another idea
  
  TODO TODAY
    A task

  ARCHIVE
    Old tasks just pasted here
