I quite dislike any format that does not provide me immediately with a 2 or 3 sentence general description of what the thing is about, of the sort like you would find at the beginning of a Wikipedia article or in the parent comment (but with a bit less detail).

Taking BRCK as an example, I see "It's the easiest, most reliable way to connect to the Internet." and some picture suggesting that this is a hardware device. Insufficient. If I page down it gets even more confusing.
