Watch CR4news on YouTube

Posted February 16, 2010 12:01 AM by Steve Melito

Have you ever wondered what some of your favorite CR4 bloggers look like? How about the way that they sound? Do they have fun at work? And considering that CR4 never sleeps, do the bloggers get out of the office much?

The answers you seek are on YouTube, my friend. Since last summer, CR4 has been quietly uploading videos to its CR4news channel there. With 21 videos now in place, it's time to share this secret with you. So what's there to watch?

How-To Videos

Alas, about half the links were broken. Do YouTube videos normally expire that quickly?

Thanks for catching this, Tornado. I'm hoping that YouTube URLs don't expire that quickly, but that may be the case. (I'll research this to be sure).

At any rate, I just updated the links so that all of the videos now work.

Suggest closeups and better sound.

Keep at it.
