The site uses a whitelist of URLs to (attempt to) keep results relevant to science and programming. In the context in which I'm using this search engine, I have no interest in (reviews on) 3 hole punches. (That's not to say I never do, but in that case I'd use Google, Reddit, etc.) The fact that results don't show up here means that they also won't show up when I'm not looking for them, which is 100% of the time when I'm using this search engine. That's a plus for me personally.
Best case would be to have relevant results in a single search engine, but that's not what I intended when building this site.
