Perhaps the smiley wink ;-) at the end of that sentence might have clued some people in to the fact that it was not meant to be taken completely seriously.

I am both heartened and disappointed by this thread, heartened that a few people came up with reasoned arguments as to the usability benefits of a case-insensitive OS. Disappointed at the far larger number of people who hit the downmod button on comments they disagree with without being able to articulate why they disagree.

I think that the latter behaviour is all too representative of Hacker News of late, unfortunately.
