To be honest, complaining that “half of the information” is in a video form is so stupid. Stick to the written sources and be happy that the other half of the information is supplied the way you want it.
Obviously there is a market for video content, and there is probably as many people liking it as disliking it. I am a dyslexictic person that can understand and remember way better when I am spoon fed the information instead of struggle through a long blog post or news site.
Please be open minded that we are different.
Valve would probably like to hear about your findings so that they can resolve this if it is verified
