As a general rule, I skip over posts that are only video. I find the spoken word and video content to be inferior to the written word in terms of sheer data transfer to my human brain. I can read and understand much faster than people can speak, so reading is more efficient.
Graphical data is great if properly prepared. See Tufte's Book "The Visual Display of Quantitative Information."
