I don't know what planet you live on. That's like saying stack overflow is in charge of making sure every excellent question/post is seen, or reddit, or hacker news...

My job is to develop features that facilitate people finding exactly what they're looking for, and ideally things they aren't looking for and don't even know exist. That's a difficult challenge though, while still retaining engagement features like comments to discuss resources, proper categorization of favorites, etc. I started a wiki to help with this but it's only maybe 25% complete. There are plenty of other ways on the site to help with that though.
