Yes, and I realized this when I start to work for a company and found myself have a lack of explaining the project with my manager and not founding new ideas to implement, and explaining this feature and why we shoud add. A programmer shoud be able to communicate with other people and explain their ideas very well, so I should stat reading one book for each thing that will affect the way i think in programming or in life. I also found that presentation skills are very important and to understand the business side. We are not going to be a business or sketches guys but theses things will help us in programming very well and the way we think.
Yes you are right, May be the little "credit" is nothing but I'm working to add more info about the authors and how it works ,Thanks for critique i loved it.
I already put the credits for Douglas Crockford at the bottom of videos, and now i puts the credits to YUI for every video .Thanks for your interest to mention about this
