Thanks to my friend Andrew, I discovered this morning a flaw in the way my "On the Go" post images were displaying in Google Reader. They were blowing way out of the window size and it looked horrible. So I opted to find a way to remove those posts from my feed.

A little bit of research found a method to add a filter to your RSS feed:

function feedFilter($query) {
	if ($query->is_feed) {
		$query->set('cat', '-375');
	return $query;

The "375" is the numerical ID of the category you want to exclude. You can exclude multiple categories by separating them with commas, i.e. set('cat', '-375,-3,-8').

This code needs to be placed in your "functions.php" file.

It's a bit annoying that Google reader caches everything it sees. What do you do when you have test posts make make their way into the cache? Though ultimately, I think it's a good thing. If a well-known villain were to post something awful, and it were to get picked up by Google reader, it would be that much harder to hide.
