I use org mode extensively, and yeah, gotta admit it's nice.
My biggest gripe is the amount of typing it still takes to annotate stuff. I often find it hard to keep up e.g. taking live notes in a class settings.
For instance, starting a new document and typing:
#+BEGIN_TITLE
Class XYZ Notes
#+END_TITLE
Then later on I wanna insert a code segment, and, gotta:
#+BEGIN_SRC javascript
$var = "ooh, cool code, bro.";
#+END_SRC
(yeah, C-c C-, s works, but I gotta remember that exists, and then also ewww generates in lowercase -- uppercase that shortcut output!)
And then I find I want a table, so lots of "|"s
There's probably better faster shortcuts for lots of this, but like everything in emacs, it's finding and learning them. Typically I need some downtime to do that, which doesn't happen if I'm e.g. trying to take notes quickly.
Anyway, despite this, I gotta agree org mode is really helpful. Happying org'ing to you!
