Comparison of a simple document in multiple formats

########### MARKDOWN ###########

Easily readable; you can hand this to someone who has never seen markdown 
before and they won't have a problem.  (You can use underscores instead of 
asterisks, but I've found asterisks make more intuitive sense 
to people who aren't familiar with the format.)  Filesize 157 bytes.

# This is a level one header
## This is a level two header
### This is a level three header

*this is italics*
**this is bold**

* This
* is a
* bulleted list.

########### HTML ###########

It can be read with a plain text editor, but it's distracting as all get out 
for casual use. Filesize 215 bytes.

<h1>This is a level one header
<h1>This is a level two header
<h1>This is a level three header

<em>this is italics</em>
<strong>this is bold</strong>

<ul>
<li>This</li>
<li>is a</li>
<li>bulleted list.</li>
</ul>

########### RTF ###########

Possible to read with a plain text editor, but as you can see, it's kind 
of painful.  Filesize 2k.

########### DOC ###########

Effectively unreadable with just a text editor; while the text is in there, 
there is binary data that means I cannot cut and paste it here. Without a 
converter or word processor, you've got a VERY tough job ahead of you.  
Filesize is 10.5k.


########### ODT ###########

Unreadable with just a text editor - these formats have styled XML 
(content.xml) inside a compressed archive. Additionally, the specifics of 
the styles may be held in a different file than the document itself.
What is below is the extracted document.xml. Filesize of the archive 
is 10.6k, and the uncompressed content.xml is 8.9k.
