I saw this linked somewhere: http://userscripts.org/scripts/show/6412. It makes Google Reader embed the actual web page from a blog post in the list view, instead of the content of the feed. From there, I found http://userscripts.org/scripts/show/8561, which is a modification of it to exclude certain feeds from doing that. I grabbed that one, and modified it myself to include specific feeds instead of exclude. Now, when I click the Penny Arcade feed, I actually see the comic (and whole page) right in my Google Reader instead of having to click through to it. Sweet. Requires Firefox, Greasemonkey.
