I went to Random.Org, converted all your names into numbers, and added a number for you for the extra tweet, blog post, Facebook mention, etc. Then, I let the computer pick a random number. It picked 5, which was Jenna Z!
Congratulations, Jenna Z!

Jenna, please email me your mailing info (firstname.lastname@example.org) so I can give it to CSN and they will ship you the yoga mat.
Thanks for entering, everyone! :)
