That's really interesting to know, thanks. I think for my purposes a lot of high-quality information isn't paid - it's academic, policy, and nonprofit sources mainly. I feel like you could make a lot of improvement for my purposes just by:

- Downweighting commercial sources and upweighting academic, government, and nonprofit sources.

- Using some measure of quality, maybe even something simple like length + reading age?

- Building big whitelists of quality sites and blacklists of low-quality sites, as picked by human curators and users

Beyond this, perhaps users could plug in sources that are particularly useful for them, including ones they have subscriptions to. I've thought it would be handy to have search results include ebooks, papers, and notes on my computer, for example.

But maybe the userbase of people who need high quality, non-subscription info is too small to get this started.

Interesting feedback. Thanks!

Maybe I was biased towards paid content because I did an enterprise search project on scientific articles before.

> users could plug in sources that are particularly useful for them

That could work if you have a local copy of the data which can be indexed. E-Book DRM might be a problem.

That was my impression. I almost always got puzzled looks when I described the idea. And most of those people were “knowledge workers”. But if you are a specialist, you already know where to look for the information you need in your area of expertise.
