I used this all the time twenty years ago. Tried it out again for some reason recently, I think at the suggestion of ChatGPT (!), for some archiving, and it actually did some damage.

I do wish there was a modern version of this that could embed the videos in some of my old blog posts so I could save them entire locally as something other than an HTML mystery blob. None of the archive sites preserve video, and neither do extensions like SingleFile. If you're lucky, they'll embed a link to the original file, but that won't help later when the original posts go offline.
