Today I rewrote the pitch for Cracked, based off the feedback I got from their writing workshop. (It boiled down to “don’t be so obvious” and “get better sources”.) I’m much happier with the pitch now.
If you have any interest in writing humorous material, I would strongly recommend that you try pitching to them a few times – they are fair, honest and uncompromising, which is what you want in feedback.
