I wonder how many people find this sort of thing more useful than a text article with a few well-placed screenshots. I can easily see how a video can be handy when explaining some highly visual and interactive environment but in this case, you're mostly staring at a dude's editor or browser while he types things and clicks things. A dude with the accent and cadence of a cartoon hypnotist, no less. The effort expended in producing a screencast must easily exceed that of writing up the same information. Not to mention ease of addressability, indexing, updatability, etc, etc, etc.
