It's true that as a visitor of a website I will often already have an idea of what it is. But when I visit it, the first thing I want to know is whether that was correct. Yes, all those in-channels imply context - but that context is often very different from place to place. We approach links we found on google differently than ads or links we found on social media and the information that's already given will differ. A simple description, or more broadly, anything that quickly makes clear what you do, isn't primarily for informing random visitors who had no idea, but for quickly getting everyone on the same page no matter where they come from. I'm all for explaining what you do in such a way that it is also helpful in taking people that already know to the next step - but please, don't skip it entirely.
