I get the desire for things to be written down rather than videoed. When I'm looking for instructions or information, I won't even bother with a video, I go straight for textual sources and it irritates me when that's not an option.
That said, I like recording audio/video because it gives me the freedom to talk about things casually in a way I just can't with a blog post. Additionally, I often get more interaction on certain topics in video than in blog posts.
Vlogs especially.
