I agree that you don't need to tell people what should probably be taken for granted - that you're all doing your best, and obviously not twiddling your thumbs all day (I'd assume a lot of your time is playing games to prep for discussion). That, and it's a bit rude and weird to question what individuals accomplish at work.
That said, I think the "exclusive content every day" statement on the premium signup page should be changed. I'm pretty happy with gb's output, but it seems like a no-brainer to change a selling-point statement that's just factually incorrect. It bothers enough people to warrant altering it, I think.
