As for the challenge, I have two sites that I have followed crashed on about 90%. I did not actually create a YT video yet. All of my traffic has come from twitter. I am VERY glad I have done this though, as it exposed me to new avenues and provides a very solid base of knowledge. I recommend it to anyone starting out, and if you make any money at all consider it icing on the cake. You're paying tuition, here, with your time and your small initial investment of a domain and hosting. Keep that in mind. I have already ventured off into other avenues, but I haven't forgotten my two crashed challenge sites, and I plan to use them as part of a blog network someday when building links. If they provide no other value than that, I'm happy.
