Nothing irritates me more than google pimping me spammy videos as an answers on simple questions.
Videos forces you to consume information slowly in a sync manner. Videos are good for sense-rich entertainment.
Information is perfectly and efficently can be (and always were) delivered at text.
Not so much video as audio. I work for a company that provides digital lending services for libraries. Guess what type of content is by far the most popular? Audiobooks. It's not even close. Most of the "videoification" of blog posts I see on youtube are basically just podcasts with somebody talking into a video camera instead of a microphone.
