The current lens should make the second question easy to find.
The first question orients.
The second question opens the conversation.
That is where the site should help.
Not by showing everything.
By making the next useful doorway obvious.
A site like this should not behave like a static archive where the reader is left to reverse-engineer the structure. It should behave more like a good conversation: answer the thing in front of us, then quietly reveal where the thought could go next.
That second question might be a related note, a source trail, a reply prompt, or a more durable piece of writing. The important part is that the reader does not have to work hard to keep going.
Depth should be available without becoming the demand.
