When learning cool bird facts I really enjoy listening to people talk - but when trying to debug or learn a new framework I absolutely insist on written documentation. I need to be able to re-read paragraphs or segue to other topics briefly and then return which is incompatible with anything audio-visual. The existence of Laracasts was actually a strong disincentive for me to go with Laravel and I've been quite happy over in Zend/Laminas land.
