Probably not worth it to you and me. For the target audience, the fact that the linked site doesn't have "tangible dimensions" (i.e. I don't know where I am "in" the site) and can't just be read front to back is already daunting.
I have relatives who have Lesko's book and just browse through it in the bathroom. It's comforting to them not only how comprehensive it is, but that in some sense it has a beginning and an end; when they finish the book, they have some kind of confidence that the percentage of programs they're aware of is now large. That might be a false confidence, but the sense it's possible keeps them reading. Hard to do that with a searchable index.
