At https://you.com we believe in choice but not force it. It will just work out of the box, but as folks shop or get really into something like coding - we have heard from many users that they like or dislike certain sources or apps. Like w3school - it's in every search engine but some folks hate it so they can downvote it.

I personally benefitted a lot from the ability to like the reddit app once and then see more real reddit results?
