I think the First Post meme has a bit of orthogonal justification to it, though: that if you spend the time to write something other than "first post," someone else will have beaten you to posting by writing less.

Priceless.

I didn't even know that was ALLOWED on Hacker News! All this time I've been going back to SlashDot when I needed to post that, and I could have been claiming first posts here.

I suspect it's not normally allowed or encouraged, but I think it is uniquely relevant and appropriate in this case.

I wasn't seriously suggesting otherwise ... It was supposed to be funny (and to subtly make the point that we really don't want that here).
