The site should answer what kind of conversation to have.
That may be more useful than a perfect bio.
A bio says:
Here is who this person is.
A better public context surface says:
Here is what this person is thinking about.
Here is where the live questions are.
Here is what might be interesting to compare notes on.
Here is what would be useful to challenge.
Here is what not to overread.
That changes the shape of the first conversation.
It gives someone a better opening.
It gives their agent a better briefing.
It turns the site from a profile into a conversation surface.
That feels closer to the point.
