I think it is nice for people to be interested in kernel design and
even if they have bad ideas, letting them discuss their ideas
generally gives them the opportunity to learn why they are bad, which
could generate good ideas in the process. microkernel designs are
nice, but Linux is not the right basis for one.

With that said, I suggest you refrain from being so quick to judge. It
is a slippery slope that can lead you to consider anyone absent from a
mental whitelist to be "a crackpot". It also causes problems when you
misidentify someone because he made an attempt to help less
knowledgeable people learn, rather than telling them with his vision
of how things work. This can happen whenever you meet new people who
would have been on your list had you known them better.

Yours truly,
Richard Yao
