I prefer text to video or audio. Text is a more 2-dimensional format – my eyes scan up and down the page looking for keywords. I read it non-linearly, reading the more interesting-looking sentences first (even multiple times), leaving the less interesting ones until the end. Text lets me follow my own attention, audio/video force me into a linear straight-jacket – I know I can rewind/fast-forward/etc, but that's still a lot more slow and painful than just darting my eyes around a page. A picture can say a lot that words can't, but that's why (hyper)text can have pictures, figures, diagrams, photos, tables, etc, embedded in it. Even embedded video clips and audio files, for those times when an audiovisual component is really adding something.
I've largely hated the slow transition of information from barebones html scrawlings to the modern video presentation format. One thing I've discovered is installing an HTML5 video speed controller extension that lets me run most videos at 2.5-3.0x speed. It really seems to help. I think part of the problem is that most videos are tuned well below the rate I like to scan in information.
I agree and also watch most videos much faster than 1x; it seems lowest-common-denominator-oriented "educational" videos require the most speedup, while with denser stuff, and some entertainment, I can only get up to 1.5-1.8x. An (un?)fortunate side-effect is that talking to most people in realtime becomes annoyingly slow; and likewise, others tell me that I'm talking too fast.
