Whoa, what the heck was that? Notice anything different? We are shifting from the old way we were doing videos, using slow, outdated software, to pulling in motion graphics design specialists to craft the look of our videos. This one was done by Daniel Black, one of four teams of contractors we’re currently working with. Tomorrow’s video will be created by a different team. It’s up to you to tell us which you like better. In the comments please include your thoughts on the new look, and which format you like better. And if you or someone you know is an expert in motion graphics software and would like to become team number five please check out our Employment Opportunities ( page.
