Its a "protocol", but perhaps that is not helpfull so lets use "method", a way of doing things. Its not a location. Like English, English is not a platform, its a method to interact with other humans, so is Nostr (or any other protocol for that matter). The point of tasking agents to rip peoples websites and nostrify them is to illustrate Nostr to the owner of that website as to what to possibilities and added value of Nostr is. So its for demonstration purposes, so they then hopefully are motivated to do it themselves for real. The reason to use AI for this is because it takes only a couple of minutes to get the demo up and running without any effort. Websites have all sorts of content, "about" pages, blogposts, videos, whateverwhatever, and all of those things can be discrete Nostr events with the appropriate kind, and subsequently render nicely in the adequate Nostr app people use. I.e. it flips the model; the content itself is now central, and the website became just another venue of displaying/accesing that content, but any Nostr app now also became such a venue. Hope this clears things up.
