Interesting enough book, but I must admit, I was surprised at the low quality of most of the popular videos and YouTubers he links from the "book". Are these people making any money out of their YouTube fame? I guess with a little dedication (produce content in regular intervals), you can still get quite far on YouTube.
Basically the guy found out that seeing talking faces in the morning lifts his mood. Perhaps that is all there is to the YouTube blogging phenomenon: people have a need to see talking faces, no matter what the faces actually say.
I'm surprised... I thought this was something very low and dumb, but the text actually makes sense and can be useful for those wanting to promote their projects in video. Not the best link ever, but an interesting enough link.
