NSUserDefaults is kinda like git

Note that like all analogies, this is not a perfect one. I find it helps me think about it though. Also, don't try to draw conclusions about performance from this analogy :)

-[NSUserDefaults setObject:forKey:] is like...
<edit file to add key and value>
git add file
git commit
dispatch_after(some time, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    [[NSUserDefaults standardUserDefaults] synchronize]
});

// Add one of these.

// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

1. Right-click on iA Writer.app in your Applications folder, select "Show Package Contents"
2. Open up Resources/English.lproj/htmlTemplate.html in your favorite text editor
3. Add a link to a CSS file in your home directory (and anything else you might want). I put mine in ~/Library/Application Support/iA Writer/themes/policus/css/styles.css and decided to load a couple of web fonts from Google. See hacked-htmlTemplate.html later this gist.
4. Save, exit
5. Create the CSS file, override default Writer styles

Now when you export to HTML from inside of Writer, your HTML file will be styled according to your your overrides. Want to share your pretty docs? Print to PDF.

Next steps: Link to a locally-hosted jQuery and write a little JS app for switching themes in browser.
