One is because Rob's a great guy and a fantastic writer, and you should be reading his comic. Yes, you. (Too much work to visit every few days? Add the comic's LiveJournal to your f-list for extra irony.)
Another is that the comic linked above contains some of my art. (Slightly modified to better fit the dialogue, as is sometimes needed...)
Yet a third reason is that that particular comic is one of the funniest PartiallyClips I've read in quite some time. And so it's only right that I link to it in my LiveJournal.
