Some people don't like to read, so what we have are streaming audio and streaming video. The Inside AdSense Blog is one of the first official search blogs to use video to answer questions at the blog. They announced they would do this the other day and then uploaded the first vcast, video cast, answering three basic AdSense questions.
Neat way to do it and it provides a more personal touch. Google asks folks to submit questions and their photos, so they can be part of the next vcast.
