Looks pretty good. I just watched one of the videos (JavaScript Arrays) and I appreciate how he showed a couple different ways to do things, encouraging experimentation. The price seems pretty reasonable for this much material. The nice thing about web development is that you really don't need much to get started, just a text editor and browser (and there are plenty of free options). This won't substitute for a college degree or anything, but learning the material would probably give you the knowledge needed to create and maintain a small business's or organization's website.
They spend all of 30 minutes on security (covering just the essential basics, it appears), so I'd probably recommend against creating a website that allows commercial transactions or accepts users' private information without some more formal training in security. But certainly it seems to provide everything needed to create informational websites. And since these days pretty much every business needs to have an informational website, there's probably a good deal of work out there for folks who can do simple sites on the cheap.
