"Thus, if I end up watching a lot of videos during the day I am actually reducing the amount I could have taken and learned that day. So me personally I rarely watch videos that are very long. Time is valuable and I have many things to do."

I feel the same, I see a trend where people try to vlog more than blog because they think it is of better value as it surely adds value But I just cannot always watch a movie with sound. Reading though I can do far more often. So I profoundly believe writing will in the end give one much more exposure than video.
