I know enough to know I don't know much :) But there's plenty of documentation out there.

My impression is that if you're not dealing with people trying to game the algorithm then it's all a lot simpler.

As to data sources - with a constrained set of sites the creation of custom adapters should be do-able I'd have thought.

Not that I have any plans. Maybe I should though :)

Edit: come to think of it, it's practically an internet law that stuff you think of already exists. So maybe I should just post an Ask HN for the link to the search engine in question...

An interesting meta-problem comes with success of a curated search engine. The sites it actually supports would themselves have to be curated as otherwise the camel's nose gets back into the tent.

Yeah, exactly. Either not successful enough to game or... Nice problem to have? Maybe?

(I have similar thoughts about diacussion fora fwiw)
