If you want to reach new people, video is one of the easiest ways to do it, people love the meaty vlog style vids, or even shorter ones for generation ADD.
I have ADHD (and I wish it was a "generation". I might have got diagnosed before age 40) and I bloody hate the tendency for everything to be videos now, especially when I'm looking for a how-to for some quick thing—household fixes, how to do something or other in Photoshop, whatever. Text is skippable, skimmable, reread-particular-bits-without-fiddling-about-able, forget-and-refer-back-to-while-you're-doing-the-thing-able. I don't want to sit still through a 6-minute video and then forget it all immediately, when I could have found and read the relevant bit in 2.
This probably doesn't apply to less immediate and specific stuff like a potential BIP vid though. I liked scribbly's video script in the other thread, and I can see how that being a video could add things that aren't there in the text alone.
