(I'm going to rewrite this, because people have made some good points in the thread.)
Most April Fools' gags in tech are lame. Only the very best ones, such as those that show hackery ingenuity, deserve much attention on HN. I propose that we, or rather you, flag the others off the front page.
After plodding through them much of March 31 (where I am), I realized I was dreading the next 24 hours of having to read so many lame stories and decide which are real. Then I thought it might turn into a positive if I appealed to you all instead. This is a plea! You don't have to do it, but in my view it will help.
A word about humorlessness, since it's bound to come up. People who complain about HN's humorlessness have a point, but not because we're against humor. We like laughing as much as anyone. It's because empirically, a culture of humor means a flood of lame humor, and HN's goal is to optimize for signal/noise ratio. As with any optimization, there are inevitably tradeoffs.
