Maybe. But shouldn't it be the other way around: Only LWers get to see the post, but not the general public? I mean I can only see the post if I'm not logged in.
Just to make it clear I mean this LW post: http://lesswrong.com/lw/jzr/my_april_fools_day_confession/
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
