Ahh sorry - I am usually totally against shortened links but: 1. Didn't know that HN would trim the long links 2. Remember the shortcodes/aliases used at xrl.

Ahh sorry - I am usually totally against shortened links but: 1. Didn't know that HN would trim the long links 2. Remember the shortcodes/aliases used at xrl.us (such as the MIT course names), although browser smart address bars and Google is just as easy. Thanks for putting the links up, I don't need to update my comment.
