I think that the WhoIsHiring account should just automatically post this. It's basically for everything that doesn't fit in the monthly Who's Hiring of Freelancer threads. Btw, this thread is fascinating. It's a great way to check the pulse of the HN crowd and a more informal way for people to "Show HN:".

I agree that the thread is fascinating. Your suggestion is a good one, since whoishiring already does this and is the only account allowed to.

Not on the first of the month, though—too crowded. Perhaps the second Friday of each month, since that's what today is. :)
