ways to insert "note to self" in an org-mode file for academic paper

["Christopher W. Ryan" <cryan@binghamton.edu>]

I'm very early in trying a transition from LaTeX to org-mode for
academic writing, trying to learn the Org way of doing things. Running
Org-mode 7.7 in Emacs 23.4.1 on Win XP.

Suppose I'm writing a draft of a research proposal and come to some part
that I may want to consider changing, after I think about it some more,
check with others, or reassess my resources. In LaTex, I'd write
something like this:

% need to look into this further, check with so-and-so

and keep writing on the next line.

How does one do this well in Org-mode? With a # comment character? Or
does this become a TODO item?

Of course, I wouldn't want that little "note to self" to appear in any
final document. But I might want it to remain in the source file, to
document my line of reasoning.

Thanks.
