I got a 404 as well. Somehow elcron missed an apostrophe in "I'm" in the address he posted. Interesting that the URL shortened version actually preserved the link integrity in this case.

Ironically, you can read an argument against shorteners on this same blog here-- http://jacquesmattheij.com/Down+with+URL+shorteners

Note: I avoid shortened links like the plague, just an interesting observation.
