How will you afford to keep the search engine up to date without expensive retraining of the entire model? My understanding is that fine-tuning will not result in the same accuracy as a full retrain.
We actually have an architecture that lets us expand the index without doing any retraining, so we can add/update pages pretty much for free.
EDIT: It looks like the answer is "no". Substituting in AstralCodexTen gives a bunch of weird occult and esoteric blogs, not rationalist blogs. These are the top results:

I don't think that is how this works.
This works by looking a web text where it talks about SlateStarCodex and seeing what URLs are associated with that text (ie, what it links to).
If the name is changed this will break completely.
