Doubtlessly a key ingredient in Cali Lewis' success is that she just is durn cute. I know that's why I looked up her podcast in the first place.
But it is also a good podcast (vodcast, videocast, whatever). It's entertaining, and often has interesting information. I watched a couple of episodes of it on my iPhone 4 over lunch in a café yesterday. (It really is an amazing new world.)
I had been vaguely wondering just how amateur or professional the production actually is. And the most recent episode tells the answer: professional! Wow, the lights alone...
I find it interesting that anybody can make decent video, even pretty good, with just an iPhone or iPod Nano. But at the same time, if you want it to be really professional, it takes a lot more work and money. Almost paradoxical, the amount of effort it takes to cross this little bridge from "good" to "really good".
