I'm curious, why use URL shortners on HN? It's not like you're constrained to 140 characters. (I'm not trying to be a jerk, just trying to understand your reasoning.)
Siracusa tweeted the links the day before, so I had them in a textfile on the desktop. Because the URLs were easier to read than the originals, I didn't think it would be an issue.
